Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, with the spread of autonomous vehicles, the need to further arrange the vehicle seat has been increasing. However, in a vehicle such as Patent Document 1, since the vehicle seat is configured to be movable in the interior space of the vehicle body, it cannot sufficiently meet the needs of occupants who want to arrange the vehicle seat in the exterior space of the vehicle body.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to provide a vehicle that can provide a sense of liberation to occupants by expanding the passenger compartment more than before and enabling the vehicle seat to be freely arranged.

Means for Solving the Problems

[0007] According to the vehicle of the present invention, the above problem is solved by a vehicle including a vehicle body and a vehicle seat disposed in the internal space of the vehicle body, wherein the vehicle body has a vehicle body floor on which the vehicle seat is disposed and an outer vehicle body wall portion disposed so as to surround the vehicle seat, the vehicle seat has a seat body on which an occupant sits and a moving device for movably attaching the seat body to the vehicle body floor, at least a part of the outer vehicle body wall portion is provided so as to be switchable between a closed position for closing the internal space of the vehicle body and an open position for opening the internal space of the vehicle body, the moving device has an operation portion operated by the occupant, and when the operation portion is operated, the seat body is moved between a reference position and an upper position moved upward from the reference position, and when at least a part of the outer vehicle body wall portion is in the open position and the seat body is in the upper position, at least a part of the seat body is disposed above at least a part of the outer vehicle body wall portion when in the closed position. With the above configuration, it is possible to realize a vehicle that can expand the passenger compartment and freely arrange the vehicle seat, thereby giving the occupant a sense of liberation. Specifically, at least a part of the outer vehicle body wall portion is switched from the reference position to the open position, and the seat body is moved upward by being operated by the occupant. Then, at least a part of the seat body moves to the external space of the vehicle body. By doing so, the passenger compartment is expanded and the seat body is moved to the external space of the vehicle body, so that a sense of liberation can be given to the occupant. In particular, since the occupant can move the vehicle seat to a preferred position by operating it himself / herself, the seat body can be arranged in various configurations.

[0008] At this time, the seat body has a seat back and a headrest provided above the seat back. When at least a part of the outer wall portion of the vehicle body is in the open position and the seat body is in the upper position, it is preferable that the upper end portion of the headrest is disposed upward beyond at least a part of the outer wall portion of the vehicle body when in the closed position. With the above configuration, since the height position (the line-of-sight position of the occupant) of the headrest moves to the external space of the vehicle body, the line-of-sight position of the occupant becomes higher than the internal space of the vehicle body, and the sense of liberation of the occupant can be further improved.

[0009] At this time, the outer wall portion of the vehicle body has an upper wall portion of the vehicle body disposed above the vehicle seat and a sunroof attached to the upper wall portion of the vehicle body and disposed at a position corresponding to the seat body. The sunroof is provided so as to be switchable between the closed position and the open position. When the sunroof is in the open position and the seat body is in the upper position, it is preferable that at least a part of the seat body is disposed upward beyond the sunroof when in the closed position. With the above configuration, since the sunroof disposed above the seat body is switched from the reference position to the open position, the passenger compartment is enlarged and the seat body rises to the external space of the vehicle body, so that a sense of liberation can be given to the occupant.

[0010] At this time, when the sunroof is in the closed position, one end portion and the other end portion of the sunroof in the front-rear direction are disposed at the same height position as the upper wall portion of the vehicle body. When the sunroof is in the open position, it is preferable that the one end portion and the other end portion are disposed at a position higher than the upper wall portion of the vehicle body. With the above configuration, by switching the entire sunroof from the reference position to the open position, the passenger compartment can be further enlarged.

[0011] At this time, when the sunroof is in the closed position, one end and the other end of the sunroof in the front-rear direction are arranged at the same height position as the upper wall portion of the vehicle body. When the sunroof is in the open position, it is preferable that the one end is arranged at the same height position as the upper wall portion of the vehicle body, and the other end is arranged at a position higher than the upper wall portion of the vehicle body. With the above configuration, by switching one side of the sunroof from the reference position to the open position, the passenger compartment can be enlarged with a simple configuration.

[0012] At this time, the vehicle has a first seat body on the vehicle body floor and a second seat body arranged behind the first seat body. The moving device moves the second seat body between the reference position and the upper position when the operation unit is operated. When the sunroof is in the open position and the second seat body is in the upper position, it is preferable that the upper end portion of the second seat body is arranged above the sunroof when it was in the closed position and above the upper end portion of the first seat body. With the above configuration, since the line-of-sight position of the occupant sitting on the rear seat body is higher than that of the front seat body, a sense of liberation can be given without blocking the line of sight of the rear occupant.

[0013] At this time, the outer wall portion of the vehicle body has a first sunroof attached to the upper wall portion of the vehicle body and a second sunroof arranged behind the first sunroof. It is preferable that at least one of the first sunroof and the second sunroof is provided so as to be switchable between the closed position and the open position. With the above configuration, since the sunroof is divided and switched from the reference position to the open position, the passenger compartment can be enlarged in various arrangements.

[0014] At this time, the vehicle has a first seat body disposed below the upper wall portion of the vehicle body on the vehicle body floor, and a second seat body disposed below the sunroof and behind the first seat body. The moving device moves the second seat body between the reference position and the upper position when the operation unit is operated. When the sunroof is in the open position and the second seat body is in the upper position, at least a part of the second seat body may be disposed above the sunroof when it was in the closed position. With the above configuration, when the sunroof disposed above the rear seat body is switched from the reference position to the open position, the passenger compartment expands and the rear seat body rises to the external space of the vehicle body. Therefore, even when the front passenger is driving, a sense of liberation can be given to the rear passenger.

[0015] At this time, the vehicle has a first seat body on the vehicle body floor and a second seat body disposed behind the first seat body. The moving device moves the first seat body and the second seat body between the reference position and the upper position when the operation unit is operated. When at least a part of the outer wall portion of the vehicle body is in the open position and the first seat body and the second seat body are in the upper position, the first seat body may be disposed at a height position different from that of the second seat body. With the above configuration, since a plurality of seat bodies can be moved respectively, the vehicle seat can be freely arranged.

[0016] At this time, the vehicle seat has a rotating device for rotatably attaching the seat body around an axis along the vertical direction with respect to the vehicle body floor. When at least a part of the outer wall portion of the vehicle body is in the open position and the seat body is in the upper position, the rotating device may rotate the seat body when operated by the passenger. With the above configuration, since the seat body can be rotated, the vehicle seat can be freely arranged.

Effect of the Invention

[0017] According to the present invention, by expanding the passenger compartment and enabling the vehicle seat to be freely arranged, a vehicle can be realized that can give a sense of liberation to the passengers. Moreover, according to the present invention, the line-of-sight position of the passenger becomes higher than the internal space of the vehicle body, and the sense of liberation of the passenger can be further improved. Also, according to the present invention, a sense of liberation can be given to the passengers. Furthermore, according to the present invention, the passenger compartment can be further expanded. In addition, according to the present invention, the passenger compartment can be expanded with a simple configuration. Moreover, according to the present invention, a sense of liberation can be given without obstructing the line of sight of the rear passengers. Also, according to the present invention, the passenger compartment can be expanded in various arrangements. In addition, according to the present invention, even when the front passenger is driving, a sense of liberation can be given to the rear passengers. Also, according to the present invention, the vehicle seat can be freely arranged.

[0021] <<Overall Configuration of Vehicle Seat>> As shown in FIGS. 1 and 2, the vehicle V1 of the first embodiment is, for example, an electric vehicle (EV vehicle) with four wheels that can be automatically driven, and includes a vehicle body 1, a vehicle seat 2 disposed in the internal space of the vehicle body 1, and a battery 3 for driving the vehicle that supplies power to an electric motor. The vehicle V1 is switchable between a manual driving mode in which the driver performs a driving operation and an automatic driving mode in which the driver's driving operation is unnecessary. In the following embodiments, the vehicle V1 is, as an example, a minivan-based camping car, but can be applied to any type of vehicle such as a sedan, wagon, SUV (Sport Utility Vehicle), etc. Further, it is not limited to an electric vehicle capable of automatic driving, and may be a vehicle that is not capable of automatic driving. Furthermore, it is not limited to an electric vehicle, and may be an engine vehicle, a hybrid vehicle equipped with both a motor and an engine for running, a vehicle equipped with a battery and a fuel cell as a power source, etc.

[0022] As shown in FIGS. 1 and 2, the vehicle body 1 has an outer wall portion 10 of the vehicle body arranged to surround the vehicle seat 2 and a vehicle body floor 15 on which the vehicle seat 2 is arranged. The outer wall portion 10 of the vehicle body partitions the internal space and the external space of the vehicle body 1. The outer wall portion 10 of the vehicle body has a bottom wall portion 11 of the vehicle body arranged below the vehicle seat 2, an upper wall portion 12 of the vehicle body arranged above the vehicle seat 2, a front wall portion 13A of the vehicle body arranged in front of the vehicle seat 2, a rear wall portion 13B of the vehicle body arranged behind the vehicle seat 2, and side wall portions 14 of the vehicle body arranged on the sides of the vehicle seat 2. The outer wall portion 10 of the vehicle body further has a sunroof 16 attached to the upper wall portion 12 of the vehicle body, a sunroof drive mechanism 17 for opening and closing the sunroof 16, a front glass 18, and a tailgate 19.

[0023] Here, the internal space of the vehicle body 1 refers to the space inside the vehicle body 1 surrounded by the upper wall portion 12 of the vehicle body, the front wall portion 13A of the vehicle body, the rear wall portion 13B of the vehicle body, the side wall portions 14 of the vehicle body, the vehicle body floor 15, the sunroof 16 before movement, the front glass 18, and the tailgate 19. The external space of the vehicle body 1 refers to the space outside the vehicle body 1 surrounded by the upper wall portion 12 of the vehicle body, the front wall portion 13A of the vehicle body, the rear wall portion 13B of the vehicle body, the side wall portions 14 of the vehicle body, the vehicle body floor 15, the sunroof 16 before movement, the front glass 18, and the tailgate 19.

[0024] The vehicle body bottom wall portion 11 separates the internal space and the external space below the vehicle V1. Devices such as the battery 3, the ECU of the automatic driving control device, and the harness are arranged on the vehicle body bottom wall portion 11. The vehicle body upper wall portion 12 separates the internal space and the external space above the vehicle V1. An opening 12a is formed in the central portion of the vehicle body upper wall portion 12. A sunroof 16 is attached to the vehicle body upper wall portion 12 so as to cover the opening 12a. That is, the vehicle body upper wall portion 12 and the sunroof 16 constitute the ceiling portion of the vehicle body 1.

[0025] The vehicle body front wall portion 13A separates the internal space and the external space in front of the vehicle V1, and the windshield 18 is attached thereto. The vehicle body rear wall portion 13B separates the internal space and the external space behind the vehicle V1, and the tailgate 19 is attached thereto. The vehicle body side wall portion 14 separates the internal space and the external space on the side of the vehicle V1, and a door for passengers to get on and off is attached thereto.

[0026] The vehicle body floor 15 has a space for housing devices such as the battery 3, the ECU of the automatic driving control device, and the harness between it and the vehicle body bottom wall portion 11. Since the vehicle V1 can house the battery 3, the ECU, the harness, and other devices below the vehicle body floor 15, the vehicle seat 2 can be moved so as not to interfere with the battery 3, the ECU, the harness, and other devices.

[0027] Note that, as shown in FIG. 1, the battery 3 is arranged behind the front end portion of the front seat body 20. Also, the battery 3 is arranged in front of the rear end portion of the rear seat body 20.

[0028] The sunroof 16 is formed of a light-transmitting material such as glass, for example, and is arranged above the vehicle seat 2. That is, the sunroof 16 is arranged at a position corresponding to the seat body 20 of the vehicle seat 2 (above the seat body 20). In addition, the sunroof 16 may be provided with a shade panel that adjusts the amount of light entering the vehicle interior from the opening 12a. The shade panel may adjust the amount of light entering the vehicle interior by changing its transparency based on the intensity of sunlight.

[0029] As shown in FIGS. 1 and 2, the sunroof 16 is attached to the upper wall portion 12 of the vehicle body so as to be openable and closable by a sunroof drive mechanism 17. That is, the sunroof 16 is provided so as to be switchable between a closed position P1 that closes the interior space of the vehicle body 1 and an open position P2 that opens the interior space of the vehicle body 1.

[0030] Here, opening the interior space of the vehicle body 1 means communicating the interior space with the exterior space. By opening the interior space of the vehicle body 1, the passenger compartment can be expanded.

[0031] Note that the passenger compartment refers to the area where the occupants can move. For example, it refers to the inner space (or the surrounding space) surrounded by the upper wall portion 12 of the vehicle body, the front wall portion 13A of the vehicle body, the rear wall portion 13B of the vehicle body, the side wall portion 14 of the vehicle body, the vehicle body floor 15, the sunroof 16 after movement, the windshield 18, and the tailgate 19. That is, when the sunroof 16 is in the open position P2, a part of the interior space and the exterior space becomes the passenger compartment.

[0032] As shown in FIG. 2, the sunroof drive mechanism 17 is a link member that enables the sunroof 16 to be opened and closed manually or by motor drive. The upper end portions of the sunroof drive mechanism 17 are respectively attached to the front end portion 16a and the rear end portion 16b of the sunroof 16, and the lower end portions are respectively attached to the peripheral portions of the opening 12a of the upper wall portion 12 of the vehicle body.

[0033] As shown in FIG. 2, when the sunroof 16 is in the closed position P1, the front end portion 16a and the rear end portion 16b of the sunroof 16 in the front-rear direction are arranged at the same height position as the upper wall portion 12 of the vehicle body, and when the sunroof 16 is in the open position P2, the front end portion 16a and the rear end portion 16b are arranged at a position higher than the upper wall portion 12 of the vehicle body.

[0034] The windshield 18 is provided in front of the vehicle seat 2 and attached to the front wall portion 13A of the vehicle body. The windshield 18 is provided at a position that ensures a view in front of the occupant sitting on the seat body 20 even when the seat body 20 of the vehicle seat 2 is moved in the vertical or horizontal direction.

[0035] The tailgate 19 is attached to the rear wall portion 13B of the vehicle body so as to be openable and closable by a tailgate drive mechanism (not shown) and has a rear glass 19a. The tailgate 19 is provided so as to be switchable between a closed position that closes the internal space of the vehicle body 1 and an open position that opens the internal space of the vehicle body 1. The rear glass 19a is provided at a position that ensures a view behind the occupant sitting on the seat body 20 even when the vehicle seat 2 is moved in the vertical or horizontal direction.

[0036] As shown in FIGS. 1 and 2, the vehicle seat 2 includes a seat body 20 having a seat back 21 and a seat cushion 22, a lifting device 30 that attaches the seat body 20 to the vehicle body floor 15 so as to be movable up and down, a rotating device 40 that attaches the seat body 20 to the vehicle body floor 15 so as to be rotatable about an axis along the vertical direction, a rail device 50 that supports the seat body 20 so as to be movable back and forth with respect to the vehicle body floor 15, and a reclining device 60 that rotatably connects the seat back 21 to the seat cushion 22.

[0037] Note that the vehicle V1 has a plurality of seat bodies 20, a plurality of lifting devices 30, a plurality of rotating devices 40, and a plurality of reclining devices 60 on the vehicle body floor 15. The lifting device 30, the rotating device 40, and the reclining device 60 are respectively provided on the plurality of seat bodies 20. However, it is not limited to this, and the lifting device 30, the rotating device 40, and the reclining device 60 may be configured to be shared by the plurality of seat bodies 20. In addition, the rail device 50 is shared by a plurality of seat bodies 20. However, it is not limited to this, and a plurality of rail devices 50 may be provided on the vehicle body floor 15, and the rail devices 50 may be provided on each of the plurality of seat bodies 20.

[0038] The seat body 20 includes a seat back 21 which is a backrest portion that supports the seated person from behind, a seat cushion 22 which is a seating portion that supports the seated person from below, and a headrest 23 which supports the head of the seated person. The headrest 23 is provided above the seat back 21. Therefore, when the occupant sits on the seat body 20, the upper end portion of the headrest 23 is at substantially the same height position as the line of sight position of the occupant.

[0039] The lifting device 30 includes a link mechanism 31 that moves the seat body 20 up and down relative to the vehicle body floor 15, and a lifting operation portion 32 that is operated by the occupant. The link mechanism 31 is attached to the seat cushion 22 and moves the seat cushion 22 up and down relative to the vehicle body floor 15. The seat body 20 can be moved up and down relative to the vehicle body floor 15 when the link mechanism 31 is moved by a drive motor.

[0040] The lifting operation portion 32 is, for example, a button operated by the occupant and is provided on the seat body 20. When the lifting operation portion 32 is operated by the occupant, the drive motor of the link mechanism 31 is driven. Note that the lifting operation portion 32 may be provided on the vehicle body side wall portion 14, or may be provided separately from the vehicle body 1 or the vehicle seat 2 like a remote control.

[0041] The occupant can adjust the height of the seat body 20 to a desired position by operating the drive motor of the link mechanism 31 by pressing the button of the lifting operation portion 32. Note that the configuration is not limited to adjusting the height of the seat body 20 by controlling the drive motor. For example, a configuration in which the height of the seat body 20 is adjusted by manually moving an operation lever may also be acceptable.

[0042] As shown in FIGS. 1 and 2, the lifting device 30 moves the seat body 20 between a reference position P3 and an upper position P4 that is above the reference position P3 when the lifting operation unit 32 is operated by an occupant. As shown in FIG. 2, when the sunroof 16 is in the open position P2 and the seat body 20 is in the upper position P4, the upper end portion of the seat body 20 (the upper end portion of the headrest 23) is disposed above the sunroof 16 when it is in the closed position P1.

[0043] The occupant switches the sunroof 16 of the vehicle outer wall portion 10 to the open position P2 and operates the lifting operation unit 32 to move the seat body 20 upward. By doing so, the occupant can move the headrest 23 of the seat body 20 to the external space of the vehicle body 1 and raise the line of sight position higher than the vehicle outer wall portion 10. Therefore, a sense of liberation can be given to the occupant.

[0044] In this way, since the passenger compartment can be expanded and the seat body 20 can be moved to the external space of the vehicle body 1, the amount of movement of the seat body 20 in the height direction can be significantly increased. In particular, since the occupant can move the seat body 20 to a preferred position by operating the lifting operation unit 32 himself / herself, the seat body 20 can be arranged in various configurations.

[0045] The rotating device 40 is a device that rotatably moves the seat body 20 with respect to the vehicle body floor 15 and has a rotation operation unit 41 that is operated by an occupant. The rotating device 40 is attached below the lifting device 30 and rotatably moves the seat body 20 and the lifting device 30 with respect to the vehicle body floor 15. The seat body 20 becomes rotatable with respect to the vehicle body floor 15 when a drive motor provided in the rotating device 40 is controlled. Note that the rotation operation unit 41 may be provided on the vehicle side wall portion 14 in the same manner as the lifting operation unit 32, or may be provided separately from the vehicle body 1 or the vehicle seat 2 like a remote control.

[0046] The occupant can adjust the orientation of the seat body 20 to a desired position by operating the drive motor through a button pressing operation on the rotation operation unit 41. Note that the configuration is not limited to adjusting the orientation of the seat body 20 by controlling the drive motor. For example, a configuration in which the orientation of the seat body 20 is adjusted by manually moving a rotation operation lever may also be acceptable.

[0047] The rotation device 40 rotates the seat body 20 when it is operated by the occupant when the seat body 20 is in the reference position P3 or the upper position P4. Furthermore, the rotation device 40 rotates the seat body 20 when it is operated by the occupant when the sunroof 16 is in the open position P2 and the seat body 20 is in the upper position P4.

[0048] In this way, since the seat body 20 can be rotated even when it is in the raised state, the occupant can rotate the seat body 20 to a preferred orientation by operating the rotation operation unit 41 by himself / herself. Therefore, the seat body 20 can be arranged in more various configurations.

[0049] The rail device 50 is disposed between the seat body 20 and the vehicle body floor 15 in the vertical direction, is fixed to the vehicle body floor 15, and mainly includes left and right lower rails 51 extending in the front-rear direction of the seat and left and right upper rails 52 slidably supported along the lower rails 51.

[0050] The occupant can adjust the seat body 20 to a desired position in the front-rear direction by operating a rail operation lever. Note that the configuration is not limited to adjusting the position of the seat body 20 in the front-rear direction by manually moving the rail operation lever. For example, a configuration in which the position of the seat body 20 in the front-rear direction is adjusted by controlling a drive motor may also be acceptable.

[0051] The reclining device 60 is a device that rotatably connects the seat back 21 to the seat cushion 22 and can lock the seat back 21. While the state of the seat back 21 is in the unlocked state, the occupant can recline the seat back 21. When the reclining operation lever is released when the reclining angle reaches the desired angle, it returns to the locked state.

[0052] The occupant can recline the seat back 21 to a desired angle by operating the reclining operation lever. Note that the configuration is not limited to manually moving the reclining operation lever to adjust the inclination angle of the seat back 21. For example, a configuration in which the inclination angle of the seat back 21 is adjusted by controlling a drive motor may also be acceptable.

[0053] In this way, when the seat body 20 is moved to the external space of the vehicle body 1 by the lifting device 30 and the rail device 50, the direction and inclination angle of the seat can be changed by the rotating device 40 and the reclining device 60.

[0054] <Second Embodiment> Next, the vehicle V2 of the second embodiment will be described with reference to FIG. 3. Note that descriptions of the content overlapping with the above-described vehicle V1 will be omitted. In the vehicle V2 of the second embodiment, the configurations of the sunroof 116 and the sunroof drive mechanism 117 of the vehicle outer wall portion 110 are mainly different from those of the vehicle V1.

[0055] The vehicle V2 includes a battery 103 and a plurality of seat bodies 120. Specifically, it has a front seat body 120A on the vehicle body floor 115, a rear seat body 120B disposed rearward of the front seat body 120A, a plurality of lifting devices 130, and a plurality of rotating devices 140.

[0056] As shown in FIG. 3, the sunroof 116 is attached to the upper wall portion 112 of the vehicle body such that the rear side can be opened and closed by a sunroof drive mechanism 117. That is, the sunroof 116 is provided so as to be switchable between a closed position P1 that closes the internal space of the vehicle body 101 and an open position P2 that opens the internal space of the vehicle body 101. Note that the sunroof 116 may be attached such that the front side can be opened and closed.

[0057] As shown in FIG. 3, the sunroof drive mechanism 117 is a link member that enables the sunroof 116 to be opened and closed manually or by motor drive. The upper end portions of the sunroof drive mechanism 117 are respectively attached to the rear end portion 116b of the sunroof 116, and the lower end portions are attached to the peripheral portion of the opening 112a of the upper wall portion 112 of the vehicle body.

[0058] As shown in FIG. 3, when the sunroof 116 is in the closed position P1, the front end portion 116a and the rear end portion 116b of the sunroof 116 in the front-rear direction are arranged at the same height position as the upper wall portion 112 of the vehicle body. When the sunroof 116 is in the open position P2, the front end portion 116a is arranged at the same height position as the upper wall portion 112 of the vehicle body, and the rear end portion 116b is arranged at a position higher than the upper wall portion 112 of the vehicle body.

[0059] As shown in FIG. 3, the elevating device 130 moves the front seat body 120A and the rear seat body 120B between a reference position P3 and upper positions P4a and P4b that are above the reference position P3 when an elevating operation portion 132 is operated by an occupant. As shown in FIG. 3, when the sunroof 116 is in the open position P2 and the front seat body 120A and the rear seat body 120B are in the upper positions P4a and P4b, the upper end portions of the seat body 120 (the upper end portions of the front headrest 123A and the rear headrest 123B respectively) are arranged above the sunroof 116 when it was in the closed position P1.

[0060] When the sunroof 116 is in the open position P2 and the front seat body 120A and the rear seat body 120B are in the upper positions P4a and P4b, the front seat body 120A is arranged at a height position different from that of the rear seat body 120B. Specifically, the upper end of the rear headrest 123B is arranged at a position higher than the upper end of the front headrest 123A.

[0061] The upper end of the rear headrest 123B is arranged above and higher than the upper end of the front headrest 123A beyond the sunroof 116 when in the closed position P1. Therefore, since the line-of-sight position of the occupant sitting on the rear seat body 120B is higher than that of the front seat body 120A, a sense of liberation can be given without blocking the line of sight of the rear occupant.

[0062] In this way, when the seat body 120 is moved to the external space of the vehicle body 101 by the lifting device 130 and the rail device 150, the direction and tilt angle of the seat can be changed by the rotating device 140 and the reclining device 160.

[0063] <Third Embodiment> Next, the vehicle V3 of the third embodiment will be described with reference to FIG. 4. Note that descriptions of the contents overlapping with the above-described vehicles V1 and V2 are omitted. In the vehicle V3 of the third embodiment, the configurations of the front sunroof 216A, the rear sunroof 216B, and the sunroof drive mechanism 217 of the vehicle body 201 are mainly different from those of the vehicles V1 and V2.

Similarly, the upper end portions of the rear sunroof drive mechanisms 217 are respectively attached to the front end portion 216Ba and the rear end portion 216Bb of the rear sunroof 216B, and the lower end portions are attached to the peripheral portion of the opening 212a of the upper wall portion 212 of the vehicle body.

[0067] As shown in FIG. 4, the elevating device 230 moves the front seat body 220A and the rear seat body 220B between a reference position P3 and upper positions P4a, P4b that are moved upward from the reference position P3 when the elevating operation portion 232 is operated by an occupant.

[0068] When the front sunroof 216A and the rear sunroof 216B are in the open positions P2a, P2b and the front seat body 220A and the rear seat body 220B are in the upper positions P4a, P4b, the front seat body 220A is disposed at a height position different from that of the rear seat body 220B. Specifically, the upper end portion of the rear headrest 223B is disposed at a position lower than the upper end portion of the front headrest 223A.

[0069] In this way, when the seat body 220 is moved to the external space of the vehicle body 201 by the lifting device 230 and the rail device 250, the direction and inclination angle of the seat can be changed by the rotating device 240 and the reclining device 260.

[0070] <Fourth Embodiment> Next, the vehicle V4 of the third embodiment will be described with reference to FIG. 5. Note that descriptions of content overlapping with the above-described vehicles V1 to V3 are omitted. In the vehicle V4 of the fourth embodiment, the configurations of the sunroof 316 and the sunroof drive mechanism 317 of the vehicle outer wall portion 310 are mainly different from those of the vehicles V1 to V3.

[0071] The vehicle V4 has a battery 303 and a plurality of seat bodies 320. Specifically, it has a front seat body 320A on the vehicle body floor 315, a rear seat body 320B disposed rearward of the front seat body 320A, a plurality of lifting devices 330, and a plurality of rotating devices 340. At this time, the front seat body 320A is disposed below the vehicle body upper wall portion 312 on the vehicle body floor 315, and the rear seat body 320B is disposed below the sunroof 316.

[0072] As shown in FIG. 5, the sunroof drive mechanism 317 is a link member that enables the sunroof 316 to be opened and closed manually or by motor drive. The upper end portion of the sunroof drive mechanism 317 is attached to the front end portion 316a and the rear end portion 316b of the sunroof 316, respectively, and the lower end portion is attached to the peripheral portion of the opening 312a of the vehicle body upper wall portion 312.

[0073] As shown in FIG. 5, the lifting device 330 moves the rear seat body 320B between a reference position P3 and an upper position P4 that is higher than the reference position P3 when the lifting operation portion 332 is operated by an occupant.

[0074] When the sunroof 316 is in the open position P2 and the rear seat body 320B is in the upper position P4, the upper end of the rear headrest 323B is arranged at a position lower than the upper end of the front headrest 323A.

[0075] The occupant can move the rear headrest 323B of the rear seat body 320B to the outside space of the vehicle body 301, making the line-of-sight position higher than the outer wall portion 310 of the vehicle body. Therefore, a sense of liberation can be given to the occupant. Furthermore, even when the driver is driving, a sense of liberation can be given to the occupants behind the driver.

[0076] In this way, when the seat body 320 moves to the outside space of the vehicle body 301 by the lifting device 330 and the rail device 350, the direction and inclination angle of the seat can be changed by the rotating device 340 and the reclining device 360.

[0077] <Fifth Embodiment> Next, the vehicle V5 of the fifth embodiment will be described with reference to FIGS. 6 and 7. Note that descriptions of the content overlapping with the above-described vehicles V1 to V4 will be omitted.

[0078] As shown in FIGS. 6 and 7, the vehicle body 401 includes an outer wall portion 410 of the vehicle body arranged to surround the vehicle seat 402, and a vehicle body floor 415 on which the vehicle seat 402 is arranged.

[0079] The outer wall portion 410 of the vehicle body includes a right front slide door 411, a right rear slide door 412, a left front slide door 413, and a left rear slide door 414 as slide doors that enable the occupants to get on and off. Each slide door partitions the internal space and the external space on the side of the vehicle V5.

[0080] As shown in FIGS. 6 and 7, each sliding door is attached to the outer wall portion 410 of the vehicle body so as to be openable and closable. That is, each sliding door is provided so as to be switchable between a closed position P1 that closes the internal space of the vehicle body 401 and an open position P2 that opens the internal space of the vehicle body 1.

[0081] As shown in FIGS. 6 and 7, the vehicle seat 402 includes a seat body 420 having a seat back 421 and a seat cushion 422, a lifting device 430 for attaching the seat body 420 to the vehicle body floor 415 so as to be movable up and down, a rotating device 440 for attaching the seat body 420 to the vehicle body floor 415 so as to be rotatable about an axis along the vertical direction, a rail device 450 for supporting the seat body 420 to be movable left and right with respect to the vehicle body floor 415, a reclining device for pivotally connecting the seat back 421 to the seat cushion 422, and an awning device 470 attached to the upper end portion of the outer wall portion 410 of the vehicle body.

[0082] The seat body 420 is a bench type extending in the left - right direction. The seat body 420 is moved left and right with respect to the vehicle body floor 415 between a lateral position P4 moved laterally (outward) from a reference position P3 by the rail device 450.

[0083] The rail device 450 is disposed between the seat body 420 and the vehicle body floor 415 in the vertical direction, fixed to the vehicle body floor 415, and includes two lower rails 450a extending in the left - right direction and two upper rails 450b slidably supported along the lower rails 450a. The rail device 450 is provided for each of the plurality of seat bodies 420.

[0084] Note that the battery 403 for driving the vehicle is disposed behind the front upper rail 450b in the front seat body 420 as shown in FIG. 7. Also, the battery 403 is disposed in front of the rear lower rail 450a in the rear seat body 420.

[0085] As shown in FIGS. 6 and 7, the rail device 450 moves the seat body 420 between a reference position P3 and a lateral position P4 that is laterally (outward) of the reference position P3 when the rail operation lever is operated by the occupant. For example, as shown in FIG. 7, when the left front slide door 413 is in the open position P2 and the seat body 420 is in the lateral position P4, the seat end 420a of the seat body 420 is disposed laterally (outward) of the left front slide door 413 when it was in the closed position P1.

[0086] The occupant switches the left front slide door 413 of the vehicle outer wall portion 410 to the open position P2 and operates the rail operation lever to move the seat body 420 laterally. By doing so, the occupant can move the seat end 420a of the seat body 420 to the external space of the vehicle body 401 and make the line of sight position outside the vehicle outer wall portion 410. Therefore, a sense of liberation can be given to the occupant.

[0087] In this way, since the passenger compartment can be expanded and the seat body 420 can be moved to the external space of the vehicle body 401, the amount of movement of the seat body 420 in the vehicle width direction can be significantly increased. In particular, since the occupant can move the seat body 420 to a preferred position by operating the rail operation lever himself / herself, the seat body 420 can be arranged in various configurations.

[0088] The awning device 470 is provided on the upper surface of the vehicle outer wall portion 410 and has a front awning portion 471 and a rear awning portion 472 that are used as a rain shield and a sunshade. The front awning portion 471 and the rear awning portion 472 are movably attached to the vehicle outer wall portion 410. That is, the front awning portion 471 and the rear awning portion 472 are provided so as to be switchable between a storage position that overlaps the upper surface of the vehicle outer wall portion 410 in the vertical direction and a use position that projects outward with respect to the vehicle outer wall portion 410. Note that the awning device 470 may be a rail type in which the front awning portion 471 and the rear awning portion 472 slide on the upper surface of the vehicle outer wall portion 410, or may be a telescopic type that expands and contracts.

[0089] When the front seat body 420 is in the lateral position P4 and the front bracket 471 is in the use position, the front bracket 471 is disposed above the front seat body 420. When the rear seat body 420 is in the lateral position P4 and the rear bracket 472 is in the use position, the rear bracket 472 is disposed above the rear seat body 420.

[0090] In this way, when the seat body 420 is moved to the external space of the vehicle body 401 by the lifting device 430 and the rail device 450, the direction and the tilt angle of the seat can be changed by the rotating device 440 and the reclining device 460.

[0091] <Sixth Embodiment> Next, the vehicle V6 of the sixth embodiment will be described with reference to FIGS. 8 to 12. Note that the description of the content overlapping with the above-described vehicles V1 to V5 will be omitted.

Further, even when the seat body 520 is disposed in the internal space, the orientation and inclination angle of the seat can be changed, and the seat body 520 can be arranged in a preferred form at various positions.

[0104] <Seventh Embodiment> Next, the vehicle V7 of the seventh embodiment will be described with reference to FIGS. 13 to 18. Note that the description of the content overlapping with the vehicles V1 to V6 described above will be omitted. In the vehicle V7 of the seventh embodiment, the configurations of the sunroof 616 and the rail device 650 are mainly different from those of the vehicles V1 to V6.

[0105] The vehicle outer wall portion 610 includes a right front sunroof 616A attached to the vehicle upper wall portion, a right rear sunroof 616B disposed rearward of the right front sunroof 616A, a left front sunroof 616C disposed on the left side of the right front sunroof 616A, and a left rear sunroof 616D disposed rearward of the left front sunroof 616C.

[0106] As shown in FIG. 14, the front right front sunroof 616A and left front sunroof 616C are slidably attached to the upper surface of the vehicle outer wall portion 610 in the front-rear direction. That is, the right front sunroof 616A and the left front sunroof 616C open the internal space of the vehicle body 601 by moving from the front glass 670 side to the rear glass 680 side. In the present embodiment, the right front sunroof 616A and the left front sunroof 616C are configured to be openable and closable by sliding in the front-rear direction, but they may be slid in the left-right direction. Further, not limited to sliding movement, they may be configured to be openable and closable by rotating about a rotation axis extending in the left-right direction or a rotation axis extending in the front-rear direction.

[0107] The front right front sunroof 616A and the left front sunroof 616C are provided so as to be switchable between a closed position P5 that closes the interior space of the vehicle body 601 and an open position P6 that opens the interior space of the vehicle body 601, as shown in FIG. 16. The rear right rear sunroof 616B and the left rear sunroof 616D are fixed to the upper surface of the outer wall portion 610 of the vehicle body, and are arranged at positions overlapping the right front sunroof 616A and the left front sunroof 616C in the vertical direction when the right front sunroof 616A and the left front sunroof 616C move rearward.

[0108] The outer wall portion 610 of the vehicle body has a right front slide door 611, a right rear slide door 612, a left front slide door 613, and a left rear slide door 614 as slide doors that allow passengers to get on and off.

[0109] The vehicle V7 has a battery 603 and a plurality of seat bodies 620. Specifically, on the vehicle body floor 615, there are a right front seat body 620A, a right rear seat body 620B arranged behind the right front seat body 620A, a left front seat body 620C arranged on the left side of the right front seat body 620A, and a left rear seat body 620D arranged behind the left front seat body 620C.

[0110] As shown in FIG. 17, the elevating device 630 moves the seat body 620 between a reference position P7 and an upper position P8 that is moved upward from the reference position P7 by the operation of the passenger.

[0111] The rail device 650 on the rear side of the vehicle body 601 includes two lower rails 650a extending in the left - right direction, two first upper rails 650b provided on the right rear seat body 620B and slidably supported along the lower rails 650a, and two second upper rails 650c provided on the left rear seat body 620D and slidably supported along the lower rails 650a. Further, the rail device 650 further includes two first sub-rails 650d supported by the first upper rail 650b and two second sub-rails 650e supported by the second upper rail 650c.

[0112] The first sub-rail 650d and the second sub-rail 650e of the rear rail device 650 move the right rear seat body 620B and the left rear seat body 620D in the front-rear direction, respectively. Note that the front rail device 650 may also be configured to be provided with the first sub-rail 650d and the second sub-rail 650e in the same manner.

[0113] Also, as shown in FIGS. 15 to 17, a small item storage portion 620e for placing small items and a drink storage portion 620f for placing drinks are formed on the back side of the seat back 621 of the seat body 620. The seat back 621 is deformed into a desk shape by being reclined by the reclining device 660 so that the back side of the seat back 621 faces upward. Note that the seat body 620 may have a footrest 624 rotatably attached to the seat cushion 622 as shown in FIG. 18.

[0114] In this way, when the seat body 620 moves to the external space by the lifting device 630 and the rail device 650, the rotation device 640 and the reclining device 660 can change the orientation and inclination angle of the seat, and arrange the seat body 620 in a preferred form such as a footrest shape or a desk shape. Further, since the position of the seat body 620 can be finely adjusted in the front-rear direction by the first sub-rail 650d and the second sub-rail 650e, it can be arranged in a more preferred form.

[0115] Furthermore, as shown in FIG. 18, when the right front seat body 620A and the left front seat body 620C are moved to the external space, the rotating device 640 changes the directions of the seats to face each other, and the reclining device 660 changes the directions and inclination angles of the seats, so that the plurality of seat bodies 620 can be arranged in a more preferable form.

[0116] <Eighth Embodiment> Next, the vehicle V8 of the eighth embodiment will be described with reference to FIG. 19. Note that the description of the content overlapping with the above-described vehicles V1 to V7 will be omitted. In the vehicle V8 of the eighth embodiment, the sunroof 716 and the configuration of the seat body 720 are mainly different from those of the vehicles V1 to V7.

[0117] As shown in FIG. 19, the sunroof 716 is rotatably attached to the upper surface of the vehicle outer wall portion 710 by an axis extending in the front-rear direction. Specifically, the fixed end portions 716b, which are the end portions in the left-right direction of the sunroof 716, are rotatably attached to the vehicle outer wall portion 710. By moving the movable end portion 716a upward, it is provided so as to be switchable between a closed position P1 for closing the internal space of the vehicle body 701 and an open position P2 for opening the internal space of the vehicle body 701.

[0118] As shown in FIG. 10, the lifting device 730 moves the right front seat body 720A and the left front seat body 720C between a reference position P3 and an upper position P4 that is higher than the reference position P3 when the lifting operation portion 732 is operated by the occupant.

[0119] The front rail device 750 in the vehicle body 701 includes two lower rails 750a extending in the left-right direction, two first upper rails 750b provided on the right front seat body 720A and slidably supported along the lower rails 750a, and two second upper rails 750c provided on the left front seat body 720C and slidably supported along the lower rails 750a.

[0120] In addition, the seat body 720 has a massage device 770 inside the seat back 721 and the seat cushion 722. The massage device 770 operates to correct the posture of the seat occupant. The massage device 770 is, for example, an airbag. When air is enclosed inside the airbag and it bulges, the posture of the occupant is corrected. Note that the mechanism for pressing the occupant is not limited to something that bulges like an airbag or a bag body. It may also be a mechanism that presses the occupant by pressing a regular-shaped member such as a roller-shaped body, a ball-shaped body, or a block-shaped body.

[0121] In this way, when the seat body 720 is moved to the external space of the vehicle body 701 by the lifting device 730 and the rail device 750, the direction and tilt angle of the seat can be changed by the rotating device 740 and the reclining device 760. And the right front seat body 720A is arranged at a position where the massage device 770 presses the shoulder and waist of the occupant, and the left front seat body 720C is arranged at a position where the massage device 770 presses the legs of the occupant. Therefore, the occupant can be massaged in the external space of the vehicle body 701, and thus can obtain a greater sense of liberation.

[0122] Furthermore, the left front seat body 720C is rotated by the rotating device 740 so that the back side of the seat back 721 faces the right front seat body 720A side. By doing so, the occupant sitting on the right front seat body 720A can use the seat back 721 and the headrest 723 of the left front seat body 720C as a footrest.

[0123] <Embodiment 9> Next, the vehicle V9 of the ninth embodiment will be described with reference to FIGS. 20 to 24. Note that descriptions of content overlapping with the above-described vehicles V1 to V8 will be omitted.

[0124] The tailgate 819 is attached to the outer wall portion 810 of the vehicle body so as to be openable and closable, and includes a rear glass portion 819a, a gate portion 819b rotatably attached to the rear glass portion 819a, and an awning portion 819c slidably attached to the gate portion 819b. The tailgate 819 is provided so as to be switchable between a closed position P5 that closes the internal space of the vehicle body 801 and an open position P6 that opens the internal space of the vehicle body 801.

[0125] The gate portion 819b is provided at a horizontal position when the rear glass portion 819a rotates rearward, and can be used, for example, as a rain shield or sunshade for the left rear seat body 820D. The awning portion 819c extends from the gate portion 819b by sliding rearward when the gate portion 819b is in the horizontal position. The awning portion 819c can be used, for example, as a rain shield or sunshade when the left rear seat body 820D is moved to the rear position P8.

[0126] The vehicle V9 has a plurality of seat bodies 820. Specifically, on the vehicle body floor 815, there are a right front seat body 820A, a right rear seat body 820B disposed rearward of the right front seat body 820A, a left front seat body 820C disposed to the left of the right front seat body 820A, and a left rear seat body 820D disposed rearward of the left front seat body 820C.

[0127] As shown in FIG. 20, the lifting device 830 is operated by an occupant to move the seat body 820 between a reference position P3 and an upper position P4 that is above the reference position P3. For example, as shown in FIG. 20, when the sunroof 816 is in the open position P2 and each seat body 820 is in the upper position P4, the upper end portion (the upper end portion of the headrest 823) of the seat body 820 is disposed above the sunroof 816 when in the closed position P1.

[0128] The rail device 850 includes two lower rails 850a extending in the front-rear direction, two upper rails 850b slidably supported along the lower rails 850a, and two sub-rails 850c slidably supported by the upper rails 850b.

[0129] The sub-rail 850c of the left rail device 850 on the vehicle body 801 moves the right rear seat body 820B and the left rear seat body 820D in the front-rear direction, respectively. Note that the front rail device 850 may also be configured to be provided with a sub-rail 850c in the same manner.

[0130] Note that the battery 803 for vehicle driving is disposed inside the vehicle body 801 in the left-right direction relative to the right lower rail 850a on the right side of the rail device 850 in the right front seat body 820A and the right rear seat body 820B as shown in FIG. 21. Further, the battery 803 is disposed inside the vehicle body 801 in the left-right direction relative to the left lower rail 850a on the left side of the rail device 850 in the left front seat body 820C and the left rear seat body 820D.

[0131] As shown in FIG. 20, the rail device 850 is moved between the reference position P7 of the seat body 820 and the rear position P8 moved rearward (outward) from the reference position P7 by operating the rail operation lever by the occupant. For example, as shown in FIG. 20, when the tailgate 819 is in the open position P6 and the left rear seat body 820D is in the rear position P8, the left rear seat body 820D is disposed rearward of the tailgate 819 when it is in the closed position P5.

[0132] In this way, since the passenger compartment can be expanded and the seat body 820 can be moved to the external space of the vehicle body 801 by the lifting device 830 and the rail device 850, the amount of movement of the seat body 820 in the front-rear direction can be significantly increased. In particular, since the occupant can move the seat body 820 to a preferred position by operating it himself / herself, the seat body 820 can be arranged in various configurations. In addition, when the seat body 820 is moved to the external space, the orientation and inclination angle of the seat can be changed by the rotating device 840 and the reclining device 860, and the seat body 620 can be arranged at a preferred position.

[0133] A modification example of the vehicle V8 will be described below. In the modification example 1 shown in FIG. 22, the configurations of the rail device 850 and the partition 871 are mainly different compared to FIG. 21. Specifically, the lower rail 850a of the rail device 850 is formed in a shape where a portion extending in the front-rear direction intersects with a portion extending in the left-right direction. By doing so, the upper rail 850b attached to the lower rail 850a can slide with respect to the lower rail 850a not only in the front-rear direction but also in the left-right direction, and the seat body 820 can be arranged at various positions.

[0134] Note that the portion of the lower rail 850a extending in the front-rear direction is not provided on the driver's seat side where the steering wheel 870 is provided. That is, when the left front seat body 820C serving as the passenger seat is moved forward by the rail device 850, it is arranged in front of the right front seat body 820A serving as the driver's seat.

[0135] In addition, the vehicle body 801 has a partition 871 for partitioning the passenger compartment into a driver's seat side (right side region) and a passenger seat side (left side region). The partition 871 is for partitioning the private space of the occupant, is attached to the vehicle outer wall portion 810 or the vehicle body floor 815, and is provided so as to be switchable between a use position and a storage position. The partition 871 is, for example, a bellows-shaped curtain. In the use position (solid line in FIG. 22), it is extended to a position separating the driver's seat and the passenger seat, and in the storage position (dotted line in FIG. 22), it is folded and stored at a position not separating the driver's seat and the passenger seat. Note that the partition 871 may be a slide-type panel.

[0136] In the modification example 2 shown in FIG. 23, the configurations of the seat body 820 and the rail device 850 are mainly different compared to FIG. 21. Specifically, the vehicle V8 further includes a first auxiliary seat 820E disposed between the right front seat body 820A and the left front seat body 820C in the left-right direction, a second auxiliary seat 820F disposed between the right rear seat body 820B and the left rear seat body 820D in the left-right direction, and a third auxiliary seat 820G disposed between the left front seat body 820C and the left rear seat body 820D in the front-rear direction.

[0137] The first auxiliary seat 820E is moved in the left-right direction by a rail device 850 between the right front seat body 820A and the left front seat body 820C. Since the first auxiliary seat 820E does not have a seat back 821, it is a cushion seat 822 that can be seated from the front or the rear. The first auxiliary seat 820E is provided with a lifting device 830 and a rotating device 840 respectively.

[0138] The second auxiliary seat 820F is disposed at a position on the vehicle body floor 815 where the rail device 850 is not provided. The third auxiliary seat 820G is moved in the front-rear direction by a rail device 850 between the left front seat body 820C and the left rear seat body 820D. The second auxiliary seat 820F and the third auxiliary seat 820G are each provided with a lifting device 830, a rotating device 840, and a reclining device 860.

[0139] In this way, by providing a plurality of seat bodies 820, various arrangements can be achieved. In addition, the lifting device 830, the rotating device 840, and the reclining device 860 can change the orientation and inclination angles of the plurality of seats, and the seat body 820 can be arranged in a more preferred position.

[0140] In the modification 3 shown in FIG. 24, the configurations of the seat body 820 and the rail device 850 are mainly different compared to FIG. 21. Specifically, the vehicle V8 has a U-shaped seat 820H instead of the right rear seat body 820B and the left rear seat body 820D.

[0141] The U-shaped seat 820H is a bench seat that is substantially U-shaped in top view, and is provided on the rear side of the right front seat body 820A and the left front seat body 820C. The U-shaped seat 820H is moved by the U-shaped rail 850d between a reference position where the entire U-shaped seat 820H is disposed in the interior space of the vehicle body 801 and a lateral position where a part of the U-shaped seat 820H is disposed in the exterior space of the vehicle body 801.

[0142] <Tenth Embodiment> Next, the vehicle V10 of the tenth embodiment will be described with reference to FIG. 25. Note that descriptions of the content overlapping with the vehicles V1 to V9 described above are omitted. In the vehicle V10 of the tenth embodiment, the configuration of the front portion 918 and the seat body 920 is mainly different from those of the vehicles V1 to V9.

[0143] As shown in FIG. 25, the front portion 918 is formed of a light-transmitting material such as glass, for example. The front portion 918 is composed of a front portion 918a extending in the vertical direction and a rear portion 918b extending obliquely in the front-rear direction.

[0144] The front portion 918a is a windshield extending in the vertical direction and is attached to the vehicle body front wall portion 913 of the vehicle body 901. The front portion 918a is provided at a position that secures the field of view in front of the occupant sitting on the seat body 920 even when the seat body 920 is moved in the vertical direction or the horizontal direction.

[0145] The rear portion 918b is a sunroof extending in the front-rear direction, is connected to the upper end portion of the front portion 918a, and is attached to the vehicle body upper wall portion 912. The rear portion 918b is arranged to be inclined such that the rear end portion connected to the vehicle body upper wall portion 912 is higher than the front end portion connected to the front portion 918a. The rear portion 918b is disposed at a position corresponding to the seat body 920 disposed on the vehicle body floor 915 (above the seat body 920).

[0146] The vehicle V10 has a battery 903 and a plurality of seat bodies 920. Specifically, on the vehicle body floor 915, it has a front seat body 920A, a middle seat body 920B arranged behind the front seat body 920A, and a rear seat body 920C arranged behind the middle seat body 920B.

[0147] As shown in FIG. 25, the lifting device 930 moves the seat body 920 between a reference position and an upper position where the seat body 920 is moved upward from the reference position when the lifting operation unit 932 is operated by an occupant. When the middle seat body 920B and the rear seat body 920C are in the upper position, the upper end portion of the seat body 920 (the upper end portion of the headrest 923) is arranged above the upper end portion of the front portion 918a.

[0148] As shown in FIG. 25, when the front seat body 920A, the middle seat body 920B, and the rear seat body 920C are in the upper position respectively, the front seat body 920A, the middle seat body 920B, and the rear seat body 920C are arranged at different height positions from each other seat body 920. In this way, the line-of-sight height position H2 of the middle seat body 920B is higher than the line-of-sight height position H1 of the front seat body 920A, and the line-of-sight height position H3 of the rear seat body 920C is higher than the line-of-sight height position H2 of the middle seat body 920B. Therefore, a sense of liberation can be given without blocking the line of sight of the rear occupant.

[0149] In this way, since the seat body 920 can be moved by the lifting device 930 and the rail device 950, the seat body 920 can be arranged in various configurations. Also, the direction and tilt angle of the seat can be changed by the rotating device 940 and the reclining device 960, and the seat body 920 can be arranged at a preferred position.

[0150] <11th Embodiment> Next, the vehicle V11 of the 11th embodiment will be described with reference to FIG. 26. Note that the description of the content overlapping with the above-described vehicles V1 to V10 is omitted. In the vehicle V11 of the 11th embodiment, the configuration of the motion device 1070 is mainly different as compared with the vehicles V1 to V10.

[0151] As shown in FIG. 26, the vehicle outer wall portion 1010 has a sunroof 1016 provided on the vehicle upper wall portion 1012. The sunroof 1016 is slidably attached to the vehicle upper wall portion 1012 in the front-rear direction. That is, the sunroof 1016 is provided so as to be switchable between a closed position for closing the internal space of the vehicle body 1001 and an open position for opening the internal space of the vehicle body 1001.

[0152] The vehicle V11 has a battery 1003 and a plurality of seat bodies 1020. Specifically, on the vehicle body floor 1015, it has a front seat body 1020A, a middle seat body 1020B disposed rearward of the front seat body 1020A, and a rear seat body 1020C disposed rearward of the middle seat body 1020B.

[0153] Each seat body 1020 has a support portion 1024 on the outside in the seat width direction of the seat back 1021 and the seat cushion 1022. The support portion 1024 is attached so that the amount of protrusion from the seat back 1021 and the seat cushion 1022 can be adjusted. Note that the support portion 1024 may be fixed to the seat back 1021 and the seat cushion 1022.

[0154] The support portion 1024 may be attached so as to be retractable from the seat back 1021 and the seat cushion 1022. In this case, it may be automatically retractable according to the height position of the seat body 1020. Specifically, when the seat height rises to a predetermined value (for example, 50 cm or more), it may be automatically protruded to support the occupant from the left and right directions.

[0155] The seat back 1021 has first support portions 1024a attached to both side portions in the seat width direction. The first support portions 1024a support the upper body of the occupant from the left and right directions and are members for preventing the occupant from falling from the seat body 1020. Note that the first support portions 1024a may support the occupant's arm portions from below like armrests.

[0156] The seat cushion 1022 has second support portions 1024b attached to both side portions in the seat width direction. The second support portions 1024b support the lower body of the occupant from the left and right directions and are members for preventing the occupant from falling from the seat body 1020. In addition, the seat cushion 1022 has a seat band 1025 that is spanned in the seat width direction and is detachably attached to the occupant. The seat band 1025 is a member for holding the occupant when the occupant performs an abdominal muscle exercise of raising the upper body.

[0157] The headrest 1023 has an exercise device 1070 (seat handle 1071) attached to the upper end portion of the seat back 1021. The seat handle 1071 is a member that is gripped by the occupant when the occupant performs a flexible exercise of arching the upper body.

[0158] The vehicle body upper wall portion 1012 has an exercise device 1070 (roof handle 1072) attached to the rear end portion of the vehicle body 1001. The roof handle 1072 is a member that is gripped by the occupant when the occupant performs a suspension exercise of pulling up the upper body. Note that the occupant may exercise by putting a foot on the roof handle 1072.

[0159] When the sunroof 1016 is in the open position and the rear seat body 1020C is in the upper position, the upper end portion (headrest 1023) of the rear seat body 1020C is disposed above the sunroof 1016 when it was in the closed position.

[0160] FIG. 26 shows a state in which, when the rear seat body 1020C is in the upper position and the seat back 1021 is reclined rearward by the reclining device 1060, the headrest 1023 is disposed below the seat cushion 1022. In this state, the occupant can, for example, hold the seat handle 1071 and perform flexible movements, or wear the seat belt 1025 and perform abdominal muscle exercises. At this time, by tilting the headrest 1023 of the middle seat body 1020B forward, it may also serve as a footrest that supports the feet of the occupant on the back side of the headrest 1023.

[0161] Also, when the rear seat body 1020C is in the upper position and the seat back 1021 is reclined rearward by the reclining device 1060, the seat back 1021 may be made horizontal with respect to the seat cushion 1022. By doing so, the occupant can take a relaxed posture on the seat body 1020 and rest the body.

[0162] In the present embodiment, the support portion 1024, the seat belt 1025, and the seat handle 1071 are provided only on the rear seat body 1020C, but the present invention is not limited to this, and they may be provided on all the seat bodies 1020. Further, the movements performed by the occupant are not limited to the above, and each exercise device 1070 can be appropriately used according to the movement performed.

[0163] In this way, since the seat body 1020 can be moved by the lifting device 1030 and the rail device 1050, the seat body 1020 can be arranged in various configurations. Also, the direction and tilt angle of the seat can be changed by the rotating device 1040 and the reclining device 1060, and the seat body 1020 can be arranged at a preferred position.

[0164] In particular, the occupant can move the rear seat body 1020C to the external space of the vehicle body 1001, and raise the line of sight position higher than the upper wall portion 1012 of the vehicle body. Therefore, a sense of liberation can be given to the occupant. In this way, the vehicle V11 of the present embodiment can be used as a gym vehicle on which the occupant can move. Therefore, while improving the sense of liberation, the seat body 1020 can be arranged in a manner suitable for movement.

[0165] <Embodiment 12> Next, the vehicle V12 of the 12th embodiment will be described with reference to FIGS. 27 and 28. Note that descriptions of the same content as that of the vehicles V1 to V11 described above will be omitted.

[0166] The tailgate 1119 is provided so as to be switchable between a closed position for closing the internal space of the vehicle body 1101 and an open position for opening the internal space of the vehicle body 1101.

[0167] The vehicle V12 has a battery 1103 and a plurality of seat bodies 1120. Specifically, on the vehicle body floor 1115, there are a front seat body 1120A, a middle seat body 1120B arranged behind the front seat body 1120A, and a rear seat body 1120C arranged behind the middle seat body 1120B.

[0168] The seat body 1120 has support portions 1124 on the outer sides in the seat width direction of the seat cushion 1122, respectively. The support portion 1124 is, for example, an armrest that supports the occupant's arm portion and is rotatably attached to the seat cushion 1122. The support portion 1124 is rotatably attached between a storage position and a support position where the occupant's arm portion can be supported.

[0169] The support portion 1124 may be automatically rotatable according to the height position of the seat body 1120. Specifically, when the seat height rises to a predetermined value (for example, 50 cm or more), it may be automatically rotated from the storage position to the support position.

[0170] Further, the seat cushion 1122 has a seat belt 1125 that spans in the seat width direction and is detachably attached to the occupant. The seat belt 1125 is a member for preventing the occupant from falling from the seat body 1120.

[0171] As shown in FIG. 27, when the sunroof (not shown) of the vehicle body upper wall portion 1112 is opened and the front seat body 1120A and the rear seat body 1120C are in the upper position, the upper end portions (headrests 1123) of the front seat body 1120A and the rear seat body 1120C are disposed above the vehicle body upper wall portion 1112. In this state, the occupant may tilt the seat back 1121 of the middle seat body 1120B forward and use the back side of the seat back 1121 (or the headrest 1123) as a footrest for supporting the occupant's feet. Also, in this state, the occupant may use the upper surface of the vehicle body upper wall portion 1112 as a table.

[0172] Also, as shown in FIG. 28, when a sunroof (not shown) is in the open position and the front seat body 1120A and the rear seat body 1120C are in the upper position, by tilting the seat back 1121 of the middle seat body 1120B forward, the middle seat body 1120B can also be used as a desk for the occupant sitting on the front seat body 1120A. Note that in this state, the upper surface side of the vehicle body upper wall portion 1112 may be used as a footrest for supporting the feet of the occupant sitting on the rear seat body 1120C.

[0173] Further, the vehicle body 1101 has a lighting device 1180 for illuminating the interior space. The lighting device 1180 is attached to the lighting attachment portion 1180a of the vehicle body upper wall portion 1112 in the interior space of the vehicle body 1101. The lighting device 1180 is attached to be horizontally movable with respect to the lighting attachment portion 1180a. The lighting device 1180 is, for example, an LED and illuminates the upper surface of the middle seat body 1120B having a desk shape as shown in FIG. 28.

[0174] In this way, since the lifting device 1130 and the rail device 1150 can move the seat body 1120, the seat body 1120 can be arranged in various positions. Also, by the rotating device 1140 and the reclining device 1160, the orientation and tilt angle of the seat can be changed, and the seat body 1120 can be arranged at a preferred position. Furthermore, since the lighting device 1180 can illuminate the seat body 1120, the seat body 1120 can be arranged at an even more preferred position.

[0175] <The 13th Embodiment> Next, the vehicle V13 of the 13th embodiment will be described with reference to FIG. 29. Note that descriptions of content overlapping with the above-described vehicles V1 to V12 are omitted.

[0176] As shown in FIG. 29, the front portion 1218 is composed of a front part 1218a and a rear part 1218b. The vehicle body upper wall portion 1212 is mainly composed of an upper wall front portion 1212a and an upper wall rear portion 1212b. The front part 1218a, the upper wall front portion 1212a, the rear part 1218b, and the upper wall rear portion 1212b are connected in this order to form the ceiling surface of the vehicle body 1201. Note that a sunroof (not shown) is attached to the opening portion of the upper wall rear portion 1212b so as to be openable and closable.

[0177] The front part 1218a is a windshield that extends obliquely in the front-rear direction, with its front end attached to the vehicle body front wall portion 1213 of the vehicle body 1201 and its rear end attached to the upper wall front portion 1212a. The rear part 1218b is a windshield that extends obliquely in the front-rear direction, with its front end attached to the upper wall front portion 1212a and its rear end attached to the upper wall rear portion 1212b.

[0178] The vehicle V13 has a battery 1203 and a plurality of seat bodies 1220. Specifically, on the vehicle body floor 1215, there are a front seat body 1220A, a middle seat body 1220B disposed behind the front seat body 1220A, and a rear seat body 1220C disposed behind the middle seat body 1220B.

[0179] The front seat body 1220A has an elastic spring (not shown) that generates a biasing force toward the front. The front seat body 1220A moves in the direction (forward) approaching the vehicle body front wall portion 1213 with respect to the vehicle body floor 1215 by the biasing force of the elastic spring. Therefore, the occupant can perform leg muscle exercises by sitting on the front seat body 1220A, pressing the vehicle body front wall portion 1213 with the feet against the biasing force, and moving the front seat body 1220A in the direction (rearward) away from the vehicle body front wall portion 1213 with respect to the vehicle body floor 1215.

[0180] The middle seat body 1220B has an elastic spring (not shown) that generates a biasing force toward the rear. The seat back 1221 rotates in the direction (rearward) approaching the rear seat body 1220C with respect to the seat cushion 1222 by the biasing force of the elastic spring. Therefore, the occupant can perform leg muscle exercises by sitting on the rear seat body 1220C, pressing the seat back 1221 of the middle seat body 1220B with the feet against the biasing force, and moving the middle seat body 1220B in the direction (forward) away from the rear seat body 1220C.

[0181] The exercise device 1270 (roof handle 1271) is attached to the lower surface on the front side of the rear portion of the upper wall 1212b. The roof handle 1271 is a member that is gripped by an occupant when the occupant sitting on the middle seat body 1220B performs a suspension exercise of pulling up the upper body.

[0182] As shown in FIG. 29, when a sunroof (not shown) is in the open position and the rear seat body 1220C is in the upper position, the upper end portion of the rear seat body 1220C is disposed above the sunroof (i.e., the rear portion of the upper wall 1212b) when in the closed position.

[0183] When the front seat body 1220A, the middle seat body 1220B, and the rear seat body 1220C are each in the upper position, the line-of-sight height of the front seat body 1220A overlaps with the front part 1218a. The line-of-sight height of the middle seat body 1220B overlaps with the rear part 1218b. That is, the front part 1218a and the rear part 1218b are provided at positions that ensure the field of view in front of the occupant sitting on the seat body 1220 even when the seat body 1220 is moved in the vertical direction.

[0184] In this way, since the seat body 1220 can be moved by the lifting device 1230 and the rail device 1250, the seat body 1220 can be arranged in various configurations. Also, the direction and tilt angle of the seat can be changed by the rotating device 1240 and the reclining device 1260, and the seat body 1220 can be arranged at a preferred position.

[0185] In addition, the occupant can move the rear seat body 1220C to the external space of the vehicle body 1201 to make the line-of-sight position higher than the upper wall portion 1212 of the vehicle body. Therefore, a sense of liberation can be given to the occupant. The vehicle V13 of the present embodiment can be used as a gym vehicle in which the occupant can move, and while improving the sense of liberation, the seat body 1220 can be arranged in a configuration suitable for exercise.

[0186] <14th Embodiment> Next, the vehicle V14 of the 14th embodiment will be described with reference to FIG. 30. Note that descriptions of the content overlapping with the vehicles V1 to V13 described above will be omitted. In the vehicle V14 of the 14th embodiment, the configuration of the vehicle seat 1301 is mainly different from that of the vehicles V1 to V13. The vehicle seat 1301 is applied to, for example, the passenger seat in an autonomous vehicle. Note that the vehicle seat 1301 may be applied to seats other than the passenger seat.

[0187] The vehicle seat 1301 includes a seat body having a seat back 1302 and a seat cushion 1303, a rotating device 1304 for rotatably attaching the seat body to the vehicle body floor about an axis along the vertical direction, and a cushion rotating device 1305 for rotatably connecting the seat cushion 1303 to the seat back 1302.

[0188] When the occupant sitting in the driver's seat moves to the rear seat, the occupant rotates (tips up) the seat cushion 1303 with respect to the seat back 1302 by the cushion rotating device 1305 to bring the seat back 1302 and the seat cushion 1303 into a tipped-up state where they are in contact with each other. In this tipped-up state, the occupant rotates the seat body 90 degrees horizontally with respect to the vehicle body floor by the rotating device 1304, so that the occupant can move to the rear seat in a walk-through state. At this time, it may be rotated in the tipped-up state, or it may be made into the tipped-up state after rotation. Also, it may be rotated simultaneously with the tipping up.

[0189] In this way, by changing the arrangement of the seat body by the rotating device 1304 and the cushion rotating device 1305, it becomes possible to meet the need to relax in the rear seat during automatic driving. In particular, even in a compact car with a narrow interior space of the vehicle body, the occupant sitting in the driver's seat can easily move to the rear seat.

[0190] As the drive mechanisms of the rotating device 1304 and the cushion rotating device 1305, known techniques can be used, and manual drive or motor drive may be employed. The rotating device 1304 may be embedded below the vehicle body floor. In this case, it is advisable to provide a pillar member for connecting the rotating device 1304 and the seat cushion 1303.

[0191] On the back and sides of the seat back 1302 and the seat cushion 1303 of the vehicle seat 1301, hooks for hanging luggage, wireless charging devices for charging electronic devices, or USB ports for communicating with the vehicle V14 may be provided. Furthermore, a folding table or the like may be provided on the back surface of the seat cushion 1303.

[0192] Also, the passenger seat may be configured to be manually operable in a walk-through state. At this time, it is preferable that the rotation angle of the seat body can be fixed at an angle other than 90 degrees (for example, 45 degrees). By doing so, even in the walk-through state, a lateral view can be ensured.

[0193] Also, a seat belt reminder for detecting that a passenger is seated in the passenger seat may be provided. At this time, when it is detected by the seat belt reminder that a passenger is seated, it is preferable to perform control to prohibit the rotation of the seat body. Furthermore, when it is detected by the seat belt reminder that a child seat, luggage, or the like is placed on the seat body, control to prohibit the rotation of the seat body may also be performed.

[0194] <Embodiment 15> Next, the vehicle V15 of the 15th embodiment will be described with reference to FIG. 31. Note that descriptions of the content overlapping with the vehicles V1 to V14 described above will be omitted. In the vehicle V15 of the 15th embodiment, the configurations of the vehicle seat 1401 and the door panel 1450 are mainly different from those of the vehicles V1 to V14.

[0195] The vehicle seat 1401 includes a seat back 1402, a seat cushion 1403, a headrest 1404, an armrest 1405 rotatably attached to the seat back 1402, an operating device 1410 attached to the seating surface of the passenger, and a control device 1460. The armrest 1405 is rotatably attached between a storage position where it is stored on the side surface of the seat back 1402 and a support position where it can support the arm of an occupant.

[0196] As shown in FIG. 31, the seat back 1402 has a blower device 1420, a heating device 1430, and an airbag module 1440 disposed therein. The blower device 1420 is configured to blow air from a first outlet 1421 toward the seated person through a duct from the blower main body. The first outlet 1421 is provided on the surface of the central support portion 1402a of the seat back 1402 on the side of the seated person. The heating device 1430 is a heater for heating the seated person, and is provided inside the lateral support portion 1402b of the seat back 1402. The airbag module 1440 is provided below the heating device 1430 and inside the lateral support portion 1402b of the seat back 1402.

[0197] As shown in FIG. 31, the second outlet 1422 of the blower device 1420 is disposed in the seat cushion 1403. The second outlet 1422 is provided on the surfaces of the central support portion 1403a and the lateral support portion 1403b of the seat cushion 1403 on the front side.

[0198] As shown in FIG. 31, the third outlet 1423 of the blower device 1420 is disposed in the armrest 1405. The third outlet 1423 is provided at the tip portion of the armrest 1405 in the longitudinal direction and on the surface of the armrest 1405 on the side of the seated person. An armrest ventilation passage 1406 for allowing air from the blower main body to pass through is formed in the armrest 1405.

[0199] Since the armrest 1405 is rotatably attached to the seat back 1402, the position of the third air outlet 1423 can be adjusted. Therefore, the occupant can direct the air passing through the armrest ventilation passage 1406 to a preferred position by adjusting the position of the third air outlet 1423. In addition, the tip portion of the armrest 1405 in the longitudinal direction may be rotatable around the axis in the longitudinal direction of the armrest 1405. By doing so, the angle of the third air outlet 1423 provided at the tip portion of the armrest 1405 in the longitudinal direction can be adjusted, and the air can be efficiently sent to the occupant by directing the third air outlet 1423 toward the occupant.

[0200] Also, in the storage position, the armrest 1405 is provided at a position where the third air outlet 1423 does not overlap with the seat back 1402 in the left - right direction. That is, in the storage position, since the third air outlet 1423 is arranged at a position where it is not closed by the seat back 1402, air can be efficiently sent to the occupant's neck and chest.

[0201] Note that the armrest 1405 is not limited to being provided only on one side of the seat back 1402, and it is preferably provided on both the left and right sides in the seat width direction of the seat back 1402. By doing so, air can be sent to the occupant more efficiently.

[0202] The operating device 1410 includes a mat portion 1411 formed of a cushion member, a mat holding portion 1412 that detachably attaches the mat portion 1411 to the seat body, and a sensor portion 1413 provided inside the mat portion 1411.

[0203] As shown in FIG. 31, the mat portion 1411 includes a first mat portion 1411a disposed at a position corresponding to the central support portion 1402a of the seat back 1402, a second mat portion 1411b disposed at a position corresponding to the side support portion 1402b of the seat back 1402, a third mat portion 1411c disposed at a position corresponding to the upper surface of the central support portion 1403a of the seat cushion 1403, a fourth mat portion 1411d disposed at a position corresponding to the side support portion 1403b of the seat cushion 1403, and a fifth mat portion 1411e disposed at a position corresponding to the front surface of the central support portion 1403a of the seat cushion 1403.

[0204] The thickness of the cushion member at the mat bending portion 1411f, which is the connection portion of each mat portion (1411a to 1411e), is formed thinner than the thickness of the cushion member at each mat portion. Note that since the mat bending portion 1411f is disposed at the connection portion (for example, the connection portion between the central support portion 1402a and the side support portion 1402b) of the seat body, the position in the seat width direction is restricted. Therefore, it is possible to prevent the operating device 1410 from being displaced with respect to the seat body.

[0205] As shown in FIG. 31, the mat holding portion 1412 is in a string shape and is attached to the upper end of the first mat portion 1411a. By hanging the mat holding portion 1412 on the headrest pillar of the headrest 1404, the mat portion 1411 is detachably attached to the seat body. At this time, the mat portion 1411 is disposed at a position that does not overlap with the first outlet 1421 and the second outlet 1422 of the blower device 1420, the heating device 1430, and the airbag module 1440 in the front-rear direction. By doing so, it is possible to prevent the mat portion 1411 from affecting the blower device 1420, the heating device 1430, and the airbag module 1440.

[0206] As shown in FIG. 31, the sensor unit 1413 is a sheet-like pressure sensor that detects the seating pressure applied to the seating surface of the seat body when the seated person sits on the seat, and is attached inside the mat unit 1411. Here, the "seating pressure" is a value that changes periodically according to the physiological activities of the seated person, specifically breathing, in the state where the seated person is sitting on the seat body, and is the target value detected by the pressure sensor. In addition, the sensor unit 1413 may be a seating sensor that turns on or off according to the seating pressure of the seated person. Preferably, it may be a push-switch type seating sensor. Not limited to the seating sensor, it may be a heartbeat sensor, a respiration sensor, a blood pressure sensor, a pulse wave sensor, or the like.

[0207] As shown in FIG. 31, the door panel 1450 has the fourth air outlet 1424 of the blower device 1420 disposed therein. The fourth air outlet 1424 is provided on the surface of the door panel 1450 on the side of the seated person. A plurality of fourth air outlets 1424 are provided in the vertical direction and are respectively disposed at positions corresponding to the head, waist, thigh, and feet of the occupant. In addition, a door panel ventilation passage 1451 for allowing air from the blower body to pass through is formed in the door panel 1450.

[0208] The vehicle seat 1401 is applicable to the following seats. <<Health Seat>> A health seat is a seat on which an exercise for training the trunk can be performed while sitting. Conventionally, as a health seat, an exerciser seat that moves the seating surface of a vehicle seat has been proposed (for example, Japanese Patent Application Laid-Open No. 2018-086996). However, an exerciser seat that moves the seating surface like the conventional technology has a large movement of the seating surface, so there is a possibility of giving a sense of discomfort to the occupant. Therefore, a seat that further suppresses the sense of discomfort to the occupant is required. An object of the present invention is to provide a health seat that further suppresses the sense of discomfort to the occupant.

[0209] As a health seat, the vehicle seat 1401 further has a vibration device in addition to the above-described configuration. The vibration device includes a vibration unit provided at a position corresponding to the seating surface of an occupant (seated person) on the seat body, for applying vibration to the seated person, and a moving unit for moving the vibration unit toward the seated person side. The vibration unit applies stimulation to the back or buttocks of the seated person, and is provided on the seated person side inside the seat back 1402 and the seat cushion 1403. The moving unit is, for example, an air cell, and is provided on the back side or lower side (the side away from the seated person) of the vibration unit inside the seat back 1402 and the seat cushion 1403. The moving unit moves the vibration unit toward the seated person side by the operation of the seated person.

[0210] Specifically, inside the seat back 1402, the moving unit moves the vibration unit from the back side toward the seated person side by motor drive, and presses the vibration unit against the middle or lower back of the seated person. Also, inside the seat cushion 1403, the moving unit moves the vibration unit from the lower side toward the seated person side by motor drive, and presses the vibration unit against the buttocks or thighs of the seated person.

[0211] In this way, since the vibration unit is moved to the seating surface of the seat body by the moving unit only when applying vibration to the seated person, compared with a configuration in which the vibration unit is always arranged on the seating surface of the seat body, the discomfort to the seated person can be suppressed. Note that the vibration device may be provided with a pressure sensor for detecting that the vibration unit has moved to the seating surface. When the pressure sensor detects that the vibration unit has moved to the seating surface, the moving unit restricts (stops) moving the vibration unit toward the seated person side. By doing so, it is possible to suppress excessive movement of the vibration unit to the seated person side.

[0212] In this embodiment, an example of application to a vibration device has been described. However, in addition to the vibration device, it may also be applied to a notification device (a light emitting unit or a sound generating unit). In this case, the light emitting unit or the sound generating unit is moved to the seating surface of the seat body by the moving unit only when notifying the seated person with light or sound. Therefore, compared with a configuration in which the light emitting unit or the sound generating unit is always arranged on the seating surface of the seat body, the discomfort to the seated person can be suppressed. Furthermore, in addition to the notification device, it may also be applied to a detection device (a detection unit that moves on the seating surface) or a temperature adjustment device (a heater unit that moves on the seating surface).

[0213] <<Desk Seat>> A desk seat is a seat that can be used as a desk for work or study. Conventionally, as a desk seat, a seat has been proposed that can use a heater panel provided on the back of the front seat of a vehicle seat as a table (for example, International Publication No. 2018 / 086996). However, in a desk seat like the prior art, when the vehicle shakes, the table surface also shakes, which may hinder work or study. Therefore, there is a demand for a seat that can notify the occupant when the shaking is large. An object of the present invention is to provide a desk seat that can notify the occupant when the shaking is large.

[0214] The vehicle seat 1401 as a desk seat, in addition to the above-described configuration, further includes a table provided on the back of the front seat, a vibration detection device, and a notification device. The vibration detection device includes a shake detection unit that detects the shaking of the vehicle, and a transmission unit that transmits the shake information detected by the shake detection unit to the notification device. The shake detection unit detects vibrations when the vehicle passes through a connection part or a step part of a road, or vibrations when the vehicle is overtaken by a large vehicle such as a large truck. The transmission unit transmits shake information corresponding to the level of vibration to the notification device when the shake detection unit detects vibrations equal to or greater than a predetermined value.

[0215] The notification device has a light-emitting unit and a sound generation unit for notifying the occupant according to the information from the transmission unit. For example, when the vibration level is slightly high, the light-emitting unit is lit in yellow, and when the vibration level is high, the light-emitting unit is lit in red. In addition, when the vibration level is extremely high, all the illumination on the desk may be turned off so that work or study cannot be continued.

[0216] In this way, by notifying the shaking information detected by the vibration detection device with the notification device, work or study can be restricted (or prohibited). Note that, without providing a shaking detection unit, a configuration may be adopted in which the occupant is notified by the shaking information (predicted value) calculated according to the information on the unevenness of the road surface stored in the in-vehicle navigation device or the information on surrounding vehicles acquired by the imaging device. Further, the calculated predicted value may be corrected by the vehicle speed and the corrected predicted value may be displayed. In this case, in addition to the display of the predicted value, the time until the learnable state is reached may be displayed.

[0217] <<Active Seat>> The active seat is, for example, a seat that can be used as a controller for a game displayed on a smartphone. The occupant can operate the character in the game displayed on the display by alternately raising and lowering the left and right legs or tilting the body on the vehicle seat 1401.

[0218] The control device 1460 outputs the pressure value acquired from the pressure sensor of the sensor unit 1413 provided in the mat unit 1411 to the smartphone as a signal for operating the game application of the smartphone. Therefore, the occupant sitting on the vehicle seat 1401 can operate the smartphone by moving the legs and shoulders on the seat body. For this reason, there is no need to operate the smartphone by hand, and it is possible to operate by moving the body on the seat body.

[0219] Furthermore, according to the progress of the game, the seating surface of the seat body can be vibrated to allow the user to experience the game realistically. For example, in a game where a car is driven, if the left - right balance is poor, the user may be made to feel vibrations as if driving on a rough road.

[0220] Also, according to the progress of the game, the seat body may be rotated by a rotating device or moved up and down by a lifting device. At this time, the vehicle seat 1401 preferably has a support portion for preventing the occupant from falling. The support portion supports the occupant from the outside in the seat width direction and is provided, for example, on the seat cushion 1403. The support portion is attached so that the amount of protrusion from the seat cushion 1403 can be adjusted. Furthermore, it is preferable that the control device 1460 can automatically adjust the amount of protrusion according to the progress of the game. At this time, information on the situation according to the progress of the game (such as the protrusion amount of the support portion) may be displayed on the display.

[0221] <<Refresh Seat>> The refresh seat is a seat that gives the occupant a comfortable wind (cold wind, warm wind), a favorite scent, favorite music, and comfortable vibrations. The control device 1460 is assumed to perform effects such as wind, scent, music, and vibration on the seated person based on biological information (such as electrocardiogram, blood pressure, body temperature, respiration, etc.) detected by the sensor portion 1413 provided in the mat portion 1411.

[0222] Furthermore, the control device 1460 preferably has AI (artificial intelligence). In this case, the comfort level of the occupant is calculated based on the biological information detected by the sensor portion 1413, and effects corresponding to the comfort level are performed. For example, the blower device 1420 is controlled by a control device 1460 having AI (artificial intelligence), and it is assumed that the blower device 1420 sends wind suitable for the characteristics (such as being cold - intolerant or heat - intolerant) of the seated occupant to the occupant. At this time, the comfort level information may be displayed on the display.

[0223] <<Stretch Seat>> The stretch seat is a seat that allows the occupant to perform stretching exercises such as stretching and twisting the body. The stretch seat includes a seat rotation device that rotates the seat cushion 1403 relative to the seat back 1402 about a rotation axis in the front - rear direction of the seat in response to the occupant's operation, and a reclining device that rotatably connects the seat back 1402 to the seat cushion 1403 in response to the occupant's operation.

[0224] While holding the upper body with the armrest 1405, the occupant can perform a twisting motion of the lower body by rotating the seat cushion 1403 relative to the seat back 1402 using the seat rotation device.

[0225] Also, the occupant can perform a motion of arching and stretching the body by rotating the seat back 1402 relative to the seat cushion 1403 using the reclining device so that the seat back 1402 is disposed downward. At this time, information on flexibility (degree of twist, degree of elongation, etc.) may be displayed on the display.

[0226] <<Sports Gym Seat>> The sports gym seat is a seat that allows the occupant to train muscles. The vehicle seat 1401 as a sports gym seat has elastic members on each member (seat back 1402, seat cushion 1403, armrest 1405, etc.).

[0227] The occupant can perform muscle - training exercises by pressing the elastic members with the arms and legs against the biasing force. At this time, information on the training results (degree of pressing, number of presses, etc.) may be displayed on the display.

[0228] <16th Embodiment> Next, the vehicle V16 of the 16th embodiment will be described with reference to FIGS. 32 and 33. Note that descriptions of content overlapping with the above - described vehicles V1 to V15 are omitted. In the vehicle V16 of the 16th embodiment, the configurations of the vehicle seat 1501 and the door panel 1530 are mainly different from those of the vehicles V1 to V15.

[0229] As shown in FIG. 32, the vehicle seat 1501 includes a seat back 1502, a seat cushion 1503, a headrest 1504, an armrest 1505 rotatably attached to the seat back 1502, a sensor unit 1510, a blower device 1520, and a control device 1540. The armrest 1505 is rotatably attached between a storage position where it is stored on the side surface of the seat back 1502 and a support position where it can support the arm of the occupant.

[0230] The blower device 1520 is configured to blow air from the seat side outlet 1521 toward the seated person through a duct from the blower body. The seat side outlet 1521 is provided on the side surface of the armrest 1505 on the seated person side. An armrest ventilation passage 1506 for allowing air from the blower body to pass through is formed in the armrest 1505.

[0231] Since the armrest 1505 is rotatably attached to the seat back 1502, the position of the seat side outlet 1521 can be adjusted. Therefore, the occupant can direct the air passing through the armrest ventilation passage 1506 to a preferred position by adjusting the position of the seat side outlet 1521.

[0232] As shown in FIG. 33, the door panel 1530 has a movable door armrest 1531. A door side outlet 1522 of the blower device 1520 is arranged on the surface of the movable arm portion 1532 of the door armrest 1531. A movable arm ventilation passage 1533 for allowing air from the blower body to pass through is formed in the door armrest 1531.

[0233] Since the movable arm portion 1532 is attached to the door armrest 1531 so as to be slidable in the front-rear direction, the position of the door-side air outlet 1522 can be adjusted. Therefore, the occupant can direct the air passing through the movable arm ventilation passage 1533 to a preferred position by adjusting the position of the door-side air outlet 1522.

[0234] The control device 1540 may drive the blower device 1520 according to the seating state of the occupant detected by the sensor unit 1510. By doing so, the blower device 1520 can be driven only when the occupant is seated, so that power consumption can be suppressed.

[0235] <17th Embodiment> Next, the vehicle V17 of the 17th embodiment will be described with reference to FIG. 34. Note that descriptions of content overlapping with the vehicles V1 to V16 described above will be omitted.

[0236] The vehicle V17 includes a vehicle seat 1601, an instrument panel portion 1602, a first pillar portion 1603, a second pillar portion 1604, a ceiling portion 1605, a console box 1606, a sterilization device 1610, and a blower device 1620.

[0237] The sterilization device 1610 performs sterilization processes such as sterilization, disinfection, air purification, deodorization, and ventilation of the internal space of the vehicle V17. For the sterilization process of the vehicle V17, for example, ozone, which is said to have a strong sterilization effect, can be used. The sterilization process is performed by fumigating ozone into the sealed internal space of the vehicle V17 by an ozone generator.

[0238] The first slit air outlet 1623 and the second slit air outlet 1624 are fumigation ports of the ozone generator. The first slit air outlet 1623 is provided straddling the first pillar portion 1603 and the ceiling portion 1605. The second slit air outlet 1624 is provided straddling the second pillar portion 1604 and the ceiling portion 1605. Note that the first slit outlet 1623 and the second slit outlet 1624 may share the outlet of the blower device 1620. In this case, for example, the fumigation ports and the outlets are alternately arranged at intervals of 50 mm.

[0239] The disinfection treatment is started when it is detected by various sensors that there is no occupant in the vehicle V17. The vehicle V17 is locked at the start of the disinfection treatment, and the opening of the door is prohibited until the disinfection treatment is completed, thereby preventing the occupant from accidentally getting into the vehicle V17 during the disinfection treatment. At this time, it may be notified to the occupant that boarding is not possible during the disinfection treatment. After the fumigation of ozone is completed, ventilation is performed by the ventilation device to bring the air in the vehicle V17 into a state where the occupant can board. Note that at the end of the disinfection treatment, it may be notified to the occupant that it has been disinfected.

[0240] The disinfection treatment is not limited to ozone, and may be spraying of a disinfectant such as alcohol. In this case, the disinfectant liquid is stored in the chemical storage unit 1611, and is sprayed from the instrument panel outlet 1621 of the instrument panel unit 1602 into the interior space of the vehicle V17 by the blower device 1620. Note that the disinfectant liquid may be sprayed from the console box outlet 1622 of the console box 1606 into the interior space of the vehicle V17. Further, the disinfectant liquid may be sprayed using the ventilation path formed in the seat body of the vehicle seat 1601. After the spraying of the disinfectant is completed, ventilation is performed by the ventilation device to bring the air in the vehicle V17 into a state where the occupant can board.

[0241] <The 18th Embodiment> Next, the vehicle V18 of the 18th embodiment will be described with reference to FIGS. 35 and 36. Note that the description of the content overlapping with the above-described vehicles V1 to V17 is omitted.

[0242] As shown in FIGS. 35 and 36, the vehicle seat 1701 includes a seat back 1702, a seat cushion 1703, a headrest 1704, and a disinfection device 1710.

[0243] The sterilization device 1710 performs sterilization treatment on the occupants sitting on the vehicle seat 1701. The sterilization device 1710 is, for example, an LED capable of irradiating ultraviolet rays or an LED using a specific wavelength in visible light, and is disposed inside the seat back 1702, the seat cushion 1703, and the headrest 1704. Note that the shape of the LED may be a rod shape or a dot shape. Further, a cloth-like member that emits ultraviolet rays may be disposed under the skin.

[0244] As shown in FIGS. 35 and 36, the sterilization device 1710 is disposed at a position corresponding to the apocrine glands of the occupant in the seat back 1702, the seat cushion 1703, and the headrest 1704. Grooves or recesses are formed in the seat back 1702, the seat cushion 1703, and the headrest 1704, and the sterilization device 1710 is disposed in the grooves or recesses. By disposing the sterilization device 1710 in the groove or recess, it is possible to suppress the discomfort of the occupant more than when it is disposed on the seat surface.

[0245] <19th Embodiment> Next, the vehicle V19 of the 19th embodiment will be described with reference to FIGS. 37 to 39. Note that the description of the content overlapping with the above-described vehicles V1 to V18 is omitted.

[0246] As shown in FIGS. 37 and 38, the vehicle V19 is, for example, an automatically drivable four-wheel electric vehicle (EV vehicle) whose form changes during driving and boarding / alighting, and includes a longitudinally long vehicle body 1801 and a vehicle seat 1802 disposed in the internal space of the vehicle body 1801. Note that the vehicle is not limited to a four-wheel self-driving vehicle, and may be, for example, a three-wheel (front two wheels, rear one wheel) self-driving vehicle.

[0247] The vehicle V19 is switchable between a traveling mode (FIG. 37) for traveling and a boarding / alighting mode (FIG. 38) in which the occupant can board and alight. The traveling mode is a state in which the vehicle body 1801 is laid down, and the boarding / alighting mode is a state in which the vehicle body 1801 is erected. In addition, when the traveling mode and the boarding / alighting mode are switched, it is preferable to have a notification unit that allows the passenger to confirm the form change of the vehicle body 1801 and a permission operation unit that enables an operation to permit the form change of the vehicle body 1801. By doing so, for example, when two or more passengers board the vehicle, it is possible to prevent the vehicle body 1801 from operating unexpectedly.

[0248] Since the vehicle body 1801 is long in the front-rear direction and the front end portion has a rounded shape, the wind resistance is reduced in the traveling mode, and the fuel efficiency can be improved. In addition, since the internal space of the passenger compartment can be made smaller, the air conditioning performance in the internal space can be improved. Also, when the vehicle V19 is parked, it is preferable to set it to the boarding / alighting mode. By doing so, the parking space can be reduced.

[0249] The vehicle body 1801 includes an outer vehicle body wall portion 1810 that partitions the internal space and the external space of the vehicle body 1801, a door portion 1811 that allows passengers to board and alight, a front tire 1812, a rear tire 1813, a tire link portion 1814 attached to the central portion in the longitudinal direction of the outer vehicle body wall portion 1810, a display device 1830 attached to the inside of the door portion 1811, and a storage device 1840 rotatably attached to the outer vehicle body wall portion 1810.

[0250] The outer vehicle body wall portion 1810 has a charging portion 1810a for charging the vehicle V19 and a state detection sensor 1810b for detecting the state of the vehicle body 1801 at the front end portion (the position that becomes the lower end portion in the boarding / alighting mode). In addition, the outer vehicle body wall portion 1810 has an upper detection sensor 1810c for detecting an obstacle above the vehicle body 1801 at the rear end portion (the position that becomes the upper end portion in the boarding / alighting mode). The vehicle V19 can be charged, either wired or wirelessly, by the charging portion 1810a to a battery (not shown).

[0251] In addition, a control device 1850 provided on the vehicle body 1801 is detected by a state detection sensor 1810b as to whether it is in a traveling mode or an embarkation / disembarkation mode. When it is in the traveling mode, the door unit 1811 is controlled so as not to open or close. Also, when it is in the embarkation / disembarkation mode, it is controlled to restrict traveling. At this time, it is preferable that it is controlled to be able to travel at a speed equal to or lower than a predetermined speed (for example, a speed at which it is possible to travel within a parking lot) while remaining in the embarkation / disembarkation mode. By doing so, it is possible to travel within a parking lot while remaining in the embarkation / disembarkation mode.

[0252] Furthermore, when the vehicle body 1801 is deformed from the traveling mode to the embarkation / disembarkation mode, if the control device 1850 detects an obstacle (for example, the ceiling of a parking lot, etc.) above the vehicle body 1801 by the upper detection sensor 1810c, it controls to restrict the deformation of the vehicle body 1801. By doing so, it is possible to suppress interference with an obstacle above when deforming from the traveling mode to the embarkation / disembarkation mode.

[0253] The door unit 1811 is, for example, an opening / closing door such as a canopy type, a gullwing type, or a scissor door type, and is rotatably attached to the outer wall portion 1810 of the vehicle body. The door unit 1811 is attached to the rear end portion of the outer wall portion 1810 of the vehicle body so as to be openable and closable. The door unit 1811 is openable and closable in the embarkation / disembarkation mode, and is opened by the front end portion of the door unit 1811 jumping upward, enabling passengers to embark and disembark.

[0254] The tire link portion 1814 switches the vehicle body 1801 between the traveling mode and the embarkation / disembarkation mode. One end portion thereof is rotatably attached to the outer wall portion 1810 of the vehicle body, and the other end portion is fixed to the rear tire 1813. The tire link portion 1814 is rotated by a motor (not shown) to a position where the rear tire 1813 approaches the front tire 1812, thereby switching between the traveling mode and the embarkation / disembarkation mode.

[0255] The display device 1830 is a touch panel type display that can be confirmed around the vehicle body 1801. The display device 1830 displays an image acquired from a camera (not shown) that photographs the periphery of the vehicle body 1801. Also, when the occupant sets the destination using the touch panel, the vehicle V19 can be automatically driven. In addition, when the vehicle body 1801 is in the boarding and alighting form, the display device 1830 may be optically made transparent so that the forward view of the occupant sitting on the vehicle seat 1802 is not blocked by the display device 1830.

[0256] The storage device 1840 is a trunk capable of storing the luggage of the occupant. The storage device 1840 includes a storage part 1841 for placing the luggage of the occupant, a storage rotation part 1842 for rotating the storage part 1841 with respect to the outer wall part 1810 of the vehicle body, and a storage link part 1843 for holding the placement surface of the rotated storage part 1841 in a position that keeps it horizontal.

[0257] When the vehicle body 1801 is deformed from the traveling form to the boarding and alighting form, the storage part 1841 moves from the internal space of the vehicle body 1801 to the external space.

[0258] The storage rotation part 1842 rotates the storage part 1841 by motor drive according to the operation of the occupant. When the vehicle body 1801 is deformed from the traveling form to the boarding and alighting form, the storage rotation part 1842 rotates the storage part 1841 to a position where the stored luggage can be taken in and out in conjunction with the deformation from the traveling form to the boarding and alighting form. The control device 1850 provided on the vehicle body 1801 controls the storage rotation part 1842 so that the placement surface of the storage part 1841 is kept in a horizontal state by a horizontal sensor that detects the horizontal state when the vehicle body 1801 is deformed from the traveling form to the boarding and alighting form. By doing so, for example, in the traveling form, when a cup containing a beverage is placed on the storage part 1841, it is possible to prevent the beverage in the cup from spilling when it is deformed into the boarding and alighting form.

[0259] As shown in FIGS. 37 and 38, the vehicle seat 1802 includes a seat body 1820 having a seat back, a seat cushion, and a footrest, a seat drive device 1821 that rotatably attaches the seat body 1820 to the bottom surface of the vehicle outer wall portion 1810, and a seat deformation device 1822 that changes the shape of the seat body 1820.

[0260] When the vehicle body 1801 is in a traveling mode, the seat drive device 1821 rotates the seat body 1820 between a traveling position where the seat body 1820 is laid down and a boarding / alighting position where the seat body 1820 is erected when the vehicle body 1801 is in a traveling mode.

[0261] The seat deformation device 1822 changes the angles of the seat back and the footrest with respect to the seat cushion. Specifically, when the seat body 1820 is in the boarding / alighting position, the seat body 1820 is in a state where the angles of the seat back and the footrest with respect to the seat cushion are approximately 180 degrees (a bed shape that is substantially flat in the horizontal direction) by the seat deformation device 1822. When the seat body 1820 is in the traveling position, the seat body 1820 is in a state where the angles of the seat back and the footrest with respect to the seat cushion are approximately 90 degrees (a chair shape in which sitting is possible) by the seat deformation device 1822.

[0262] In this way, since the seat body 1820 is rotated by the seat drive device 1821 according to the form of the vehicle body 1801, it is possible to make the vehicle seat 1802 compact in size and easy to board and alight while making the vehicle body 1801 compact. Furthermore, since the seat body 1820 is deformed by the seat deformation device 1822 according to the form of the vehicle body 1801, it is possible to prevent the occupant's body from slipping off the seat body 1820 when changing from the traveling position to the boarding / alighting position.

[0263] A modified example of the vehicle V19 will be described below. In the modified example shown in FIG. 39, the configuration of the storage device 1840 is mainly different from that in FIG. 38.

[0264] The storage device 1840 has a storage part 1841 fixed to the tire link part 1814. When the vehicle body 1801 is deformed from the traveling form to the boarding / alighting form, the storage part 1841 moves from the internal space of the vehicle body 1801 to the external space along with the rotation of the tire link part 1814. In this way, when deforming from the traveling form to the boarding / alighting form, with a simple configuration, the storage part 1841 can be moved to a position where the stored luggage can be taken in and out.

[0265] <20th Embodiment> Next, the vehicle V20 of the 20th embodiment will be described with reference to FIG. 40. Note that the description of the content overlapping with the above-described vehicles V1 to V19 will be omitted. In the vehicle V20 of the 20th embodiment, the configuration of the vehicle body 1901 is mainly different from that of the vehicles V1 to V19.

[0266] The vehicle body 1901 includes an outer vehicle body wall part 1910 that partitions the internal space and the external space of the vehicle body 1901, a door part 1911 that enables passengers to board and alight, a front tire 1912, a rear tire 1913, a tire link part 1914 attached to the longitudinal center part of the outer vehicle body wall part 1910, a display device 1930 attached to the inside of the door part 1911, and a storage device 1940 rotatably attached to the tire link part 1914.

[0267] The outer vehicle body wall part 1910 has a configuration that is divided into two at the central part in the longitudinal direction. The front vehicle body part 1910A on the front side and the rear vehicle body part 1910B on the rear side are connected by the tire link part 1914. Note that the outer vehicle body wall part 1910 includes a charging part 1910a, a detection sensor 1910b that detects the state in which the outer vehicle body wall part 1910 is divided into two, and an upper detection sensor 1910c that detects an obstacle above the vehicle body 1901 at a position that becomes the upper end part in the boarding / alighting form.

[0268] The front body portion 1910A is provided with a door portion 1911, a front tire 1912, and a display device 1930. Also, a vehicle seat 1902 is disposed in the internal space of the front body portion 1910A. The rear body portion 1910B is provided with a rear tire 1913. Also, a storage device 1940 is disposed in the internal space of the rear body portion 1910B.

[0269] The storage device 1940 has a storage portion 1941 fixed in the internal space of the rear body portion 1910B. When the vehicle body 1901 is deformed from the traveling mode to the boarding / alighting mode, the storage portion 1941 moves to a position where the stored luggage can be taken in and out along with the rotation of the tire link portion 1914. In this way, when deforming from the traveling mode to the boarding / alighting mode, the storage portion 1941 can be moved to a position where the stored luggage can be taken in and out with a simple configuration.

[0270] <The 21st Embodiment> Next, the vehicle V21 of the 21st embodiment will be described with reference to FIG. 41. Note that descriptions of the content overlapping with the above-described vehicles V1 to V20 will be omitted. In the vehicle V21 of the 21st embodiment, the configuration of the vehicle body 2001 is mainly different from that of the vehicles V1 to V20.

[0271] The vehicle body 2001 includes an outer vehicle body wall portion 2010 that partitions the internal space and the external space of the vehicle body 2001, a door portion 2011 that enables a passenger to board and alight, a front tire 2012, a rear tire 2013, a door drive portion 2014 attached to the front side in the longitudinal direction of the outer vehicle body wall portion 2010, a display device 2030 attached to the inner side of the door portion 2011, and a storage device 2040 attached to the internal space of the outer vehicle body wall portion 2010. In the present embodiment, the positions of the front tire 2012 and the rear tire 2013 with respect to the outer vehicle body wall portion 2010 are fixed.

[0272] The door portion 2011 is attached to the outer vehicle body wall portion 2010 so as to be openable and closable, and is attached to the front end portion of the outer vehicle body wall portion 2010. The door drive unit 2014 rotates the door unit 2011 to switch the door unit 2011 between the traveling position and the boarding / alighting position. When the door unit 2011 is in the traveling position, the door unit 2011 is arranged at a closed position with respect to the outer wall portion 2010 of the vehicle body. When the door unit 2011 is in the boarding / alighting position, the rear end portion of the door unit 2011 moves upward, and the internal space of the vehicle body 2001 is opened. Note that the internal space of the vehicle body 2001 may be opened when the front end portion of the door unit 2011 moves upward.

[0273] As shown in FIG. 41, the door unit 2011 is opened by the door drive unit 2014 causing the rear end portion of the door unit 2011 to move upward, enabling passengers to board and alight. The state where the door unit 2011 is in the traveling position is the boarding / alighting form of the vehicle body 2001, and the state where the door unit 2011 is in the boarding / alighting position is the boarding / alighting form of the vehicle body 2001.

[0274] An upward detection sensor 2011a is attached to the rear end portion of the door unit 2011. When the vehicle body 2001 is deformed into the boarding / alighting form, the control device 2050 controls to limit the deformation of the vehicle body 2001 when an obstacle (for example, the ceiling of a parking lot, etc.) above the vehicle body 2001 is detected by the upward detection sensor 2011a. By doing so, it is possible to suppress interference with an obstacle above when deforming from the traveling form to the boarding / alighting form.

[0275] The seat drive device 2021 rotates the seat body 2020 between a traveling position where the seat body 2020 is laid down when the vehicle body 2001 is in the traveling form and a boarding / alighting position where the seat body 2020 is erected when the vehicle body 2001 is in the traveling form.

[0276] The seat deformation device 2022 changes the angles of the seat back and the footrest with respect to the seat cushion. Specifically, when the seat body 2020 is in the boarding / alighting position, the seat body 2020 is adjusted by the seat deformation device 2022 so that the angles of the seat back and the footrest with respect to the seat cushion are in a state of approximately 180 degrees (a bed shape that is substantially flat in the horizontal direction). When the seat body 2020 is in the traveling position, the seat body 2020 is adjusted by the seat deformation device 2022 so that the angles of the seat back and the footrest with respect to the seat cushion are in a state of approximately 90 degrees (a chair shape that allows sitting).

[0277] In this way, since the seat body 2020 is rotated by the seat drive device 2021 in accordance with the form of the vehicle body 2001, it is possible to make the vehicle seat 2002 compact in size and easy to board and alight while making the size of the vehicle body 2001 compact. Furthermore, since the seat body 2020 is deformed by the seat deformation device 2022 in accordance with the form of the vehicle body 2001, it is possible to prevent the occupant's body from slipping off the seat body 2020 when changing from the traveling position to the boarding / alighting position.

[0278] <22nd Embodiment> Next, the vehicle V22 of the 22nd embodiment will be described with reference to FIG. 42. Note that descriptions of content overlapping with the above-described vehicles V1 to V21 will be omitted.

[0279] As shown in FIG. 42, the vehicle V22 includes a vehicle body 2101, a vehicle seat 2102 disposed in the internal space of the vehicle body 2101, a vehicle drive battery 2103 that supplies power to an electric motor, a heat sink 2104 that dissipates the heat of the battery 2103, and a seat air conditioner 2130.

[0280] As shown in FIG. 42, the vehicle body 2101 has an outer vehicle body wall portion 2110 that separates the internal space and the external space of the vehicle body 2101, and a vehicle body floor 2115 on which the vehicle seat 2 is disposed. The outer vehicle body wall portion 2110 has a vehicle body bottom wall portion 2111, a vehicle body upper wall portion 2112, a vehicle body front wall portion 2113, a vehicle body rear wall portion 2114, and a vehicle body side wall portion 2116.

[0281] The vehicle body bottom wall portion 2111 separates the internal space and the external space below the vehicle V22, and devices such as the battery 2103, the heat sink 2104, the seat air conditioner 2130, the ECU of the automatic driving control device, and the harness are disposed thereon.

[0282] The heat sink 2104 is a plurality of fins provided on the upper surface of the battery 2103. The heat sink 2104 is connected to the blower passage 2133 of the seat air conditioner 2130, and dissipates the heat generated from the battery 2103 to the blower passage 2133.

[0283] The seat air conditioner 2130 includes a first blower body 2131 that sends air to the seat body 2120, a second blower body 2132 that sends air to the outside of the vehicle body 2101, a blower passage 2133 that allows the air heated by the heat from the heat sink 2104 to pass through, and a cabin connection passage 2134 that allows the air to pass from the first blower body 2131 to the seat body 2120.

[0284] The first blower body 2131 is disposed below the seat body 2120, and discharges the air heated in the blower passage 2133 toward the seat body 2120. In addition, the first blower body 2131 sucks in the air in the passenger compartment of the vehicle body 2101 (the space surrounded by the vehicle body upper wall portion 2112, the vehicle body front wall portion 2113, the vehicle body rear wall portion 2114, the vehicle body floor 2115, and the vehicle body side wall portion 2116). In this way, the first blower body 2131 can be switched between a state of discharging the air heated in the blower passage 2133 toward the seat body 2120 and a state of sucking in the air in the passenger compartment of the vehicle body 2101.

[0285] The second blower main body 2132 discharges the air heated in the blower passage 2133 to the outside, and is disposed on the rear side of the vehicle body outer wall portion 2110.

[0286] The blower passage 2133 is a hollow pipe member extending in the front-rear direction of the vehicle body 2101, with its front end connected to the vehicle body front wall portion 2113 and its rear end connected to the vehicle body rear wall portion 2114. The blower passage 2133 is provided with an openable and closable lid 2133a at its front end. When the lid 2133a is opened, air flows in from the outside. By doing so, even without driving the first blower main body 2131 or the second blower main body 2132, the air in the passenger compartment can be inhaled and discharged from the rear end of the blower passage 2133.

[0287] As shown in FIG. 42, the vehicle seat 2102 has a seat body 2120 having a seat back 2121 and a seat cushion 2122.

[0288] A cushion ventilation passage 2122a for allowing the air from the first blower main body 2131 to pass through is formed in the seat cushion 2122. The air sent from the first blower main body 2131 passes through the cushion ventilation passage 2122a and is configured to be blown out toward the seated person from the air outlets provided on the surface of the seat cushion 2122.

[0289] When the temperature in the passenger compartment of the vehicle body 2101 is low, the control device provided on the vehicle body 2101 drives the first blower main body 2131 and controls it to send the air heated in the blower passage 2133 toward the seat body 2120. When the temperature in the passenger compartment of the vehicle body 2101 is appropriate, the control device drives the second blower main body 2132 and controls it to discharge the air heated in the blower passage 2133 to the outside. When the temperature in the passenger compartment of the vehicle body 2101 is high, the control device drives the first blower main body 2131 and the second blower main body 2132 and controls it to inhale the air in the passenger compartment and discharge it to the outside. By doing so, while appropriately cooling the battery 2103, the passenger compartment can be warmed by the waste heat of the battery 2103, so that the power saving effect can be improved.

[0290] In addition, when a lithium-air battery is used as the battery 2103, the blower passage 2133 may be used for oxygen supply. By also using the blower passage 2133, the energy loss can be reduced as compared with the case where separate air flows are created.

[0291] <23rd Embodiment> Next, the vehicle V23 of the 23rd embodiment will be described with reference to FIG. 43. Note that the description of the content overlapping with the above-described vehicles V1 to V22 will be omitted.

[0292] Conventionally, a charging system capable of simultaneously charging electric vehicles has been proposed (for example, Japanese Patent Application Laid-Open No. 2021-141648). However, a charging system such as the prior art supplies power according to the priority order, but an electric vehicle with a low priority may have a long charging waiting time.

[0293] When the charging waiting time increases, there is a risk that the passenger may not notice that the charging has ended or that there is a problem with the charging while taking a nap or having a snack in the passenger compartment or being engrossed in a smartphone during charging. In addition, if a vehicle stays at a charging station for a long time, there is also a risk of causing trouble to other vehicles as they cannot charge. An object of the present invention is to provide a vehicle that can notify the passenger that the charging has ended or that there is a problem with the charging and can also consider other vehicles.

[0294] Also, usually, the use of the air conditioner provided in the vehicle is restricted during charging (for example, it enters the power saving mode). Therefore, when the charging waiting time increases, there is a risk that the passenger compartment cannot be kept at a comfortable temperature. An object of the present invention is to provide a vehicle that makes the passenger compartment a comfortable space even during charging.

[0295] As shown in FIG. 43, the vehicle V23 includes a vehicle seat 2201, a temperature control device 2210, a console box 2220, a door panel 2230, and a control device 2240. The vehicle seat 2201 has a seat back 2202, a seat cushion 2203, and a headrest 2204.

[0296] The temperature control device 2210 is a rechargeable panel member capable of heating and cooling control, and is configured by, for example, a Peltier element that radiates heat when energized in one direction and absorbs heat when energized in the other direction. As shown in FIG. 43, a plurality of temperature control devices 2210 are provided and are respectively arranged on the vehicle seat 2201, the console box 2220, and the door panel 2230. The temperature control device 2210 is detachably attached to the attachment portions provided on the vehicle seat 2201, the console box 2220, and the door panel 2230. As shown in FIG. 43, the attachment portions are arranged, for example, on the back surface portion, side surface portion, upper surface portion of the seat back 2202, the side surface portion of the seat cushion 2203, the back surface portion of the headrest 2204, the front surface portion and back surface portion of the console box 2220, the upper surface portion of the door armrest 2231 of the door panel 2230, and the like.

[0297] The temperature control device 2210 has a built-in rechargeable battery. When the temperature control device 2210 is attached to each attachment portion, power is supplied from the battery for vehicle driving provided in the vehicle body to the rechargeable battery, and the temperature control device 2210 is charged.

[0298] While the electric vehicle is being charged, the occupant can remove the temperature control device 2210 from each attachment portion and apply the temperature control device 2210 to the hand or body to adjust the body temperature. Note that the temperature control device 2210 may heat or cool the occupant's body or the indoor air in a state of being attached to the attachment portion. Further, the temperature control device 2210 may be embedded inside the pad member of the vehicle seat 2201.

[0299] When it is a certain time (for example, 5 minutes) before the charging is completed or there is a problem with the charging, the control device 2240 performs control to notify the occupant by vibrating the seat body of the vehicle seat 2201. Examples of the notification include sound or voice from a speaker provided in the vehicle V23, display by a navigation device, lighting by door lighting, etc. Further, the occupant's smartphone may be notified that the charging is completed. When the seat back 2202 is in a state where it is largely inclined with respect to the seat cushion 2203 (relaxation mode), the seat back 2202 may return to the driving state to notify the occupant that the charging is completed.

[0300] Further, when the charging station wirelessly supplies power to the vehicle V23 parked at the charging station, the charging station may perform control to automatically move the vehicle away when the charging is completed.

[0301] Further, when the vehicle V23 does not move from the charging station even after a predetermined time has elapsed since the charging is completed, the charging station may impose a penalty on the occupant. The penalty may be, for example, to reduce the awarding rate of usage points of the charging station.

[0302] <24th Embodiment> Next, the vehicle V24 of the 24th embodiment will be described with reference to FIGS. 44 to 46. Note that the description of the content overlapping with the above-described vehicles V1 to V23 will be omitted.

[0303] As shown in FIGS. 44 to 46, the vehicle body 2301 includes an outer wall portion 2310 of the vehicle body arranged to surround the vehicle seat 2302 and a vehicle body floor 2315 on which the vehicle seat 2302 is arranged.

[0304] The outer wall portion 2310 of the vehicle body has a right front curved door 2311, a right rear curved door 2312, a left front curved door 2313, and a left rear curved door 2314 as doors that allow the occupant to get on and off. As shown in FIG. 44, each door is a curved door with a curved shape that bulges outward in the vehicle width direction. Since each door has a curved concave portion on the passenger compartment side, when the seat body 2320 of the vehicle seat 2302 arranged in the internal space is rotated, a part of the seat body 2320 enters the curved concave portion, thereby suppressing interference between the seat body 2320 and the door. The curved door is particularly suitable for a seat having an armrest with a large overhang.

[0305] The right front curved door 2311 and the left front curved door 2313 are provided with hinges on the front end side in the vehicle longitudinal direction, so that the rear end side is opened. The right rear curved door 2312 and the left rear curved door 2314 are provided with hinges on the rear end side in the vehicle longitudinal direction, so that the front end side is opened. Note that the positions of the hinges of each door are not limited to this. For example, each door may be a so-called double-opening type in which hinges are provided on the front end side and the rear end side, and either one is opened.

[0306] As shown in FIGS. 44 to 46, the vehicle seat 2302 includes a seat body 2320, a rail device 2330 that supports the seat body 2320 so as to be movable left and right or back and forth with respect to the vehicle body floor 2315, and a partition 2350 for partitioning the passenger compartment into a right region and a left region.

[0307] The vehicle V24 has a plurality of seat bodies 2320. Specifically, on the vehicle body floor 2315, there are a right front seat body 2320A, a right rear seat body 2320B arranged behind the right front seat body 2320A, a left front seat body 2320C arranged on the left side of the right front seat body 2320A, and a left rear seat body 2320D arranged behind the left front seat body 2320C.

[0308] As shown in FIG. 44, the rail device 2330 is arranged between the seat body 2320 and the vehicle body floor 2315 in the vertical direction, and includes left and right rails 2331 extending in the left and right direction and front and rear rails 2332 extending in the front and rear direction. The left and right rails 2331 support the right rear seat body 2320B so as to be movable left and right with respect to the vehicle body floor 2315. The front and rear rails 2332 support the left front seat body 2320C and the left rear seat body 2320D so as to be movable back and forth with respect to the vehicle body floor 2315.

[0309] As shown in FIG. 44, the movable storage unit 2340 includes a storage unit 2341 for storing the luggage of the occupant and a storage unit rail 2342 extending in the front-rear direction. The storage unit rail 2342 supports the storage unit 2341 so as to be movable back and forth with respect to the vehicle body floor 2315.

[0310] As shown in FIG. 44, the storage unit rail 2342 moves the storage unit 2341 in the direction of arrow A. The left and right rails 2331 move the right rear seat body 2320B in the direction of arrow B. In this way, when moving the right rear seat body 2320B in the direction of arrow B, first, by moving the storage unit 2341 in the direction of arrow A, it is possible to prevent the right rear seat body 2320B from interfering with the storage unit 2341. Note that the direction in which the storage unit rail 2342 extends is not limited to this, and any direction in which the storage unit 2341 is moved so as not to interfere with the seat body 2320 may be used.

[0311] In this way, the occupant can move or rotate the seat body 2320 to a preferred position so as not to interfere with other members (doors, storage units, etc.), so that the seat body 2320 can be arranged in various configurations.

[0312] The partition 2350 is a panel for partitioning the private space of the occupant, and is provided on the outer wall portion 2310 of the vehicle body. The partition 2350 extends in the front-rear direction and divides the passenger compartment into a right region and a left region. Note that the partition 2350 may be detachably attached to the outer wall portion 2310 of the vehicle body or the vehicle body floor 2315. Further, it may be provided so as to be switchable between a use position and a storage position. In addition, the partition 2350 may be provided with an air outlet for sending air from a blower device (not shown) to the occupant. At this time, it is preferable that a plurality of air outlets be provided at different heights.

[0313] Since the occupant can move the seat body 2320 to a preferred position while securing a private space, the seat body 2320 can be arranged in various configurations.

[0314] A modification of the vehicle V24 will be described below. In Modification 1 shown in FIG. 45, the configuration of the left and right partition portions 2351 is mainly different as compared with FIG. 44.

[0315] The left and right partition portions 2351 are panels for partitioning the private space of the occupant and are provided on the vehicle outer wall portion 2310. The left and right partition portions 2351 extend in the vehicle width direction and divide the passenger compartment into a front region and a rear region. The left and right partition portions 2351 have a rotating desk 2361 that can be used as a desk by the occupant sitting on each seat body 2320. The rotating desk 2361 is provided so as to be switchable between a use position (solid line in FIG. 45) where the occupant uses it as a desk and a storage position (dotted line in FIG. 45).

[0316] In Modification 2 shown in FIG. 46, the configurations of the left and right partition portions 2351, the front and rear partition portions 2352, and the fixed storage portion 2370 are mainly different as compared with FIG. 44.

[0317] The left and right partition portions 2351 and the front and rear partition portions 2352 are panels for partitioning the private space of the occupant and are provided on the vehicle outer wall portion 2310. The left and right partition portions 2351 extend in the vehicle width direction and divide the passenger compartment into a front region and a rear region. The front and rear partition portions 2352 extend in the front-rear direction and divide the passenger compartment into a right region and a left region.

[0318] The left and right partition parts 2351 and the front and rear partition parts 2352 have a slide desk 2362 for a passenger sitting on each seat body 2320 to use as a desk. The slide desk 2362 is provided so as to be switchable between a position far from the passenger sitting on the seat body 2320 (solid line in FIG. 46) and a position close to the sitting passenger (dotted line in FIG. 46). Therefore, the passenger can move the slide desk 2362 to a preferred position and use it.

[0319] The vehicle seat 2302 has a fixed storage part 2370 for the passenger to store luggage. As shown in FIG. 46, the fixed storage parts 2370 are respectively provided near each seat body 2320. The fixed storage parts 2370 are detachably attached to the vehicle outer wall part 2310 or the vehicle body floor 2315. Therefore, the passenger can attach the fixed storage part 2370 to a preferred position and use it.

[0320] <25th Embodiment> Next, the vehicle V25 of the 25th embodiment will be described with reference to FIG. 47. Note that descriptions of the content overlapping with the above-described vehicles V1 to V24 will be omitted.

[0321] As shown in FIG. 47, the vehicle body 2401 has a vehicle outer wall part 2410 arranged so as to surround the vehicle seat 2402 and a vehicle body floor 2415 on which the vehicle seat 2402 is arranged.

[0322] The vehicle outer wall part 2410 has a right curved door 2411 and a left curved door 2412 as doors that allow passengers to get on and off. As shown in FIG. 47, each door is a curved door having a curved shape bulging outward in the vehicle width direction.

[0323] As shown in Fig. 47, the vehicle seat 2402 includes a seat body 2420, a rail device 2430 that supports the seat body 2420 so as to be movable back and forth with respect to the vehicle body floor 2415, and a storage portion 2440 for storing the luggage of the passengers.

[0324] The seat body 2420 is a seat that is substantially circular in top view, and includes a seat back 2421 provided at the center of the seat body 2420 and a donut-shaped seat cushion 2422 provided at the peripheral edge of the seat back 2421. The seat back 2421 is a backrest portion that supports the back of the seated person. The seat cushion 2422 is a seating portion that supports the seated person from below.

[0325] For example, the seat body 2420 can accommodate four passengers, and includes a first seat body 2420A, a second seat body 2420B, a third seat body 2420C, and a fourth seat body 2420D. Recesses are formed at positions corresponding to the first seat body 2420A to the fourth seat body 2420D of the seat cushion 2422 so that the passengers can sit easily. Note that the number of passengers who can sit on the seat body 2420 is not limited to four.

[0326] The seat body 2420 is attached to the vehicle body floor 2415 so as to be rotatable about the vertical axis. The first seat body 2420A to the fourth seat body 2420D each rotate to a driving position facing the steering wheel 2450. The first seat body 2420A to the fourth seat body 2420D are each locked so as not to rotate at the driving position facing the steering wheel 2450. In this way, since the seat body 2420 can rotate to the position (driver's seat) facing the steering wheel 2450, the driver can be easily replaced.

[0327] In addition, in order to prohibit driving by a passenger without a driver's license, a non-driving seat may be provided on a part of the seat body 2420. For example, in FIG. 47, when the first seat body 2420A and the second seat body 2420B are used as the driver's seats and the third seat body 2420C and the fourth seat body 2420D are used as the non-driving seats, the first seat body 2420A and the second seat body 2420B can rotate lockably at the driving positions facing the steering wheel 2450 respectively. And the third seat body 2420C and the fourth seat body 2420D cannot rotate lockably at the driving positions facing the steering wheel 2450 respectively. In this way, since the non-driving seats are not locked at the driving positions facing the steering wheel 2450, driving is prohibited. Therefore, a passenger without a driver's license can also ride on the seat body 2420.

[0328] As shown in FIG. 47, the rail device 2430 moves the seat body 2420 in the front-rear direction when the rail operation lever is operated by a passenger. When the passenger operates the rail operation lever, the seat body 2420 moves forward, so that the seat body 2420 serving as the driver's seat can be moved to a position closer to the steering wheel 2450. Note that only a part of the seat body 2420 (for example, the first seat body 2420A) may be separated from the seat body 2420 and moved to a position closer to the steering wheel 2450.

[0329] <26th Embodiment> Next, the vehicle V26 of the 26th embodiment will be described with reference to FIGS. 48 and 49. Note that the description of the content overlapping with the vehicles V1 to V25 described above will be omitted. In the vehicle V26 of the 26th embodiment, compared with the vehicles V1 to V25, the configurations of the seat body 2520 and the rear curved door 2513 are mainly different.

[0330] As shown in FIGS. 48 and 49, the vehicle body 2501 has an outer vehicle body wall portion 2510 arranged to surround the vehicle seat 2502 and a vehicle body floor 2515 on which the vehicle seat 2502 is arranged.

[0331] The outer wall portion 2510 of the vehicle body has a right curved door 2511, a left curved door 2512, and a rear curved door 2513 as doors that allow passengers to get on and off. As shown in FIG. 48, the rear curved door 2513 is a curved door having a curved shape that bulges toward the rear side in the front-rear direction.

[0332] As shown in FIGS. 48 and 49, the vehicle seat 2502 has a seat body 2520 and a rotating device 2560 that rotatably attaches the seat body 2520 around an axis along the vertical direction with respect to the vehicle body floor 2515.

[0333] The seat body 2520 is a seat that is substantially circular in top view, and has a seat back 2521 provided at the center of the seat body 2520, a donut-shaped seat cushion 2522 provided at the peripheral edge of the seat back 2521, and a seat storage portion 2523 provided above the seat back 2521. The seat back 2521 is a backrest portion that supports the back of the seated person. The seat cushion 2522 is a seating portion that supports the seated person from below. The seat storage portion 2523 is a storage portion that stores the luggage of the passenger.

[0334] As shown in FIG. 48, the seat cushion 2522 is disposed at a position where the peripheral edge of the seat cushion 2522 enters the curved concave portions of the right curved door 2511 and the left curved door 2512. By making each door a curved door, the size of the seat cushion 2522 can be maximized. <27th Embodiment> Next, the vehicle V27 of the 27th embodiment will be described with reference to FIGS. 50 and 51. Note that descriptions of the content overlapping with the above-described vehicles V1 to V26 are omitted.

[0335] As shown in FIGS. 50 and 51, the vehicle body 2601 includes an outer wall portion 2610 of the vehicle body arranged to surround the vehicle seat 2602, a vehicle body floor 2615 on which the vehicle seat 2602 is arranged, an instrument panel portion 2630, an operation button 2640 attached to the vehicle seat 2602, a steering wheel 2650, a rail device 2660, and a rotating device 2670.

[0336] The outer wall portion 2610 of the vehicle body includes a door portion 2611 as a door that allows passengers to get on and off, and a door pocket 2612 provided on the passenger compartment side of the door portion 2611. The door pocket 2612 is provided in the door portion 2611 in a state of being divided into front and rear parts.

[0337] The instrument panel portion 2630 includes a footrest 2631 that supports the feet of the passengers sitting on the seat body 2620 from below, and a table 2632 that serves as a desk for the passengers.

[0338] The footrest 2631 is rotatably attached to the instrument panel portion 2630, and is rotatably switched between a use position (FIG. 50) where it can support the feet of the passengers and a storage position (FIG. 51) where it is stored on the side surface of the instrument panel portion 2630. When the operation button 2640 is pressed by the passenger, the footrest 2631 is rotated between the use position and the storage position by operating a footrest drive motor (not shown). When the footrest 2631 is in the use position, the footrest 2631 is arranged at a position higher than the chest (heart position) of the passenger.

[0339] When the footrest 2631 is in the use position, the rearview mirror provided on the ceiling surface on the passenger compartment side of the outer wall portion 2610 of the vehicle body may be configured to move up and down or move in the left - right direction to avoid interference with the footrest 2631. Further, the rearview mirror may be integrated with the windshield to avoid interference with the footrest 2631.

[0340] In addition to being configured to rotate, the footrest 2631 may be configured to move up and down or to move in the left - right direction. By freely driving the footrest 2631, the position can be adjusted according to the preference of the occupant. Also, by arranging the position of the footrest 2631, the occupant can perform exercises using the footrest 2631.

[0341] The table 2632 is rotatably attached to the instrument panel portion 2630 and is rotatably switched between a use position (FIG. 50) that can be used by the occupant and a storage position (FIG. 51) stored on the side surface of the instrument panel portion 2630. When the operation button 2640 is pressed by the occupant, a table drive motor (not shown) operates, and the table 2632 rotates between the use position and the storage position.

[0342] The operation button 2640 is a button pressed by the occupant and is provided on the seat body 2620 of the vehicle seat 2602. Specifically, the operation button 2640 is attached to the tip of the armrest 2623 provided on the seat body 2620. Note that the position of the operation button 2640 is not limited to the tip of the armrest 2623 and may be provided separately from the vehicle body 2601 or the vehicle seat 2602 like a remote control. In this case, it is preferable that the remote control be stored in the door pocket 2612 of the door portion 2611. Also, a pocket for storing the remote control may be provided in the instrument panel portion 2630 or in a partition for partitioning the private space of the occupant.

[0343] The steering wheel 2650 is a driving steering wheel operated by the driving occupant and is provided on the instrument panel portion 2630. The steering wheel 2650 is provided so as to be switchable between a use position (FIG. 51) where the occupant can drive and a storage position (FIG. 50) stored in the storage recess 2630a formed inside the instrument panel portion 2630.

[0344] When the driver does not need the steering wheel 2650 during automatic driving, the driver can store the steering wheel 2650 in the storage position. By doing so, it is possible to prevent the steering wheel 2650 from interfering with the seat body 2620, the footrest 2631, and the table 2632 when the seat body 2620, the footrest 2631, and the table 2632 are moved. Note that the position where the steering wheel 2650 is stored is not limited to the position formed inside the instrument panel portion 2630. For example, the steering wheel 2650 may be moved up and down so as not to interfere with the seat body 2620, the footrest 2631, and the table 2632.

[0345] Also, when the steering wheel 2650 is in the storage position, the deployment of the airbag may be restricted (the deployment amount may be reduced or prohibited). The airbag is provided on the ceiling surface on the passenger compartment side of the vehicle outer wall portion 2610 and on the seat body 2620, and is deployed between the passenger and the windshield. When the footrest 2631 is in the use position, the airbag provided on the ceiling surface is deployed. When the footrest 2631 is in the storage position, the airbag provided on the seat body 2620 is deployed.

[0346] As shown in FIGS. 50 and 51, the vehicle seat 2602 includes a seat body 2620 having a seat back 2621 and a seat cushion 2622, an armrest 2623 rotatably attached to the seat back 2621, and a seat lever 2624 attached to the seat cushion 2622.

[0347] The vehicle V27 has a plurality of seat bodies 2620. Specifically, on the vehicle body floor 2615, it has a right front seat body 2620A and a left front seat body 2620B disposed on the left side of the right front seat body 2620A.

[0348] The rail device 2660 is disposed between the seat body 2620 and the vehicle body floor 2615 in the vertical direction, and moves the seat body 2620 in the left - right direction with respect to the vehicle body floor 2615. The occupant can manually move the rail operation lever to adjust the position of the seat body 2620. Alternatively, the position of the seat body 2620 may be adjusted to a desired position by operating the drive motor provided in the rail device 2660 through the button pressing operation of the operation button 2640.

[0349] The rotating device 2670 is attached below the seat body 2620 and movably rotates the seat body 2620 relative to the vehicle body floor 2615. The occupant can manually move the seat lever 2624 to adjust the orientation of the seat body 2620. Alternatively, the orientation of the seat body 2620 may be adjusted to a desired position by operating the drive motor provided in the rotating device 2670 through the button pressing operation of the operation button 2640.

[0350] When the seat body 2620 is moved inward in the left - right direction, the rail device 2660 moves the seat body 2620 to a position where they are close to each other. At this time, the seat levers 2624 provided on the seat body 2620 are arranged at positions where they do not interfere with each other. For example, when the seat bodies 2620 are moved to positions close to each other, the seat lever 2624 of the right - front seat body 2620A is housed in the recess formed in the seat cushion 2622 of the left - front seat body 2620B, and the seat lever 2624 of the left - front seat body 2620B is housed in the recess formed in the seat cushion 2622 of the right - front seat body 2620A. By doing so, even if the seat levers 2624 are arranged at positions protruding from the seat body 2620, the seat bodies 2620 can be moved to positions where they abut against each other.

[0351] Also, when the seat body 2620 is moved outward in the left - right direction, the rail device 2660 may move the seat body 2620 to a position where it is in close contact with the door portion 2611. By the door portion 2611 and the seat body 2620 being in close contact, the air - conditioning performance in the interior space of the vehicle body 2601 can be improved.

[0352] In addition, since a gap is formed between the front and rear door pockets 2612, interference between the seat body 2620 and the door pocket 2612 can be suppressed when the seat body 2620 is rotated. In addition, when the seat body 2620 is rotated, a recess for avoiding interference may be formed in the pillar so as to avoid interference between the seat body 2620 and the pillar of the vehicle outer wall portion 2610.

[0353] <28th Embodiment> Next, the vehicle V28 of the 28th embodiment will be described with reference to FIG. 52. Note that descriptions of the content overlapping with the vehicles V1 to V27 described above will be omitted.

[0354] The vehicle seat 2702 is a convertible cross seat. As shown in FIG. 52, it has a seat body 2720 having a seat back 2721 and a seat cushion 2722, an armrest 2723 rotatably attached to the seat back 2721, and a conversion device (not shown) for attaching the seat back 2721 to the seat cushion 2722 so as to be movable back and forth.

[0355] The conversion device moves the seat back 2721 from the forward position (solid line in FIG. 52) to the backward position (dotted line in FIG. 52) with respect to the seat cushion 2722 so as to convert the orientation of the seat body 2720 by 180 degrees in the front-rear direction of the vehicle body 2701. The occupant can manually move the seat back 2721 to change the front-rear orientation of the seat body 2720. Note that the orientation of the seat body 2720 may be changed by operating a drive motor provided in the conversion device by pressing the operation button 2740.

[0356] When the seat back 2721 is switched from the forward position to the backward position by the conversion device, the armrest 2723 is rotated so as to match the position of the occupant's arm with respect to the seat back 2721. At this time, the positions of the upper and lower surfaces of the armrest 2723 are reversed. Therefore, it is preferable that the operation buttons 2740 are provided on both the upper and lower surfaces of the armrest 2723.

[0357] Note that the operation buttons 2740 may be provided on the front end surface of the armrest 2723 so that they can be operated even when the positions of the upper and lower surfaces of the armrest 2723 are reversed. Further, the armrest 2723 may be switched in position by sliding in the front-rear direction.

[0358] In the above embodiment, the case where the vehicle is an automobile has been described as a specific example. However, it is not particularly limited, and in addition to trains, buses, etc., it can also be used as an airplane, a ship, etc.

[0359] In the above embodiment, the vehicle according to the present invention has been mainly described. However, the above embodiment is merely an example for facilitating the understanding of the present invention, and does not limit the present invention. The present invention can be changed and improved without departing from its gist, and it goes without saying that equivalents of the present invention are included therein.
